How to find maximum and minimum value in java using for loop. MIN_VALUE' and loop alone will take care of everything.
How to find maximum and minimum value in java using for loop Loop through data from 0 to data. Add a comment | 4 Answers Sorted by: Reset to default 2 . MAX_VALUE (yes, MAX value) and max to `Integer. 0. split in order to find entries for a particular k value. I am struggling with this code. Just start off with highest = Integer. There are two-dimensional arrays as shown below. Initialize your smallest value to Integer. g using stream, generate n number between min and max // randomRandom(min, max) example of getting one random number between min and max // randomMath(min, max): other way similar to randomRandom(min, max) // randomThreadLocalRandom(): just for a random number without constrain // It is effective way I guess you are trying to get the minimum value from the current input and last minimum value. An example: a = [1, 3, 7, 2] You initialize largest = 0. Follow answered Feb 8, 2022 at 15:21 . Initialize min_element and max_element with the first element of the array. The most common method to find and print the largest element of a Java array is to iterate over each element of the array and compare each element with the Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Visit the blog Save your product for a later comparison. g. At the end of your loop you can simply print out maxIndex1, maxIndex2, minIndex1, and minIndex2. But i have a hard to find out the solution. This is why you get the max of the array at the end. MIN_VALUE;) I can tell you how to calculate average min and max without arrays. nextInt(); } int min = numbers [0]; // Need to initialize it here outside the loop for (int i = 1 ; i < numbers. Set values to both ’max’ and ’min’ as the first number of the list. comparing:. The value parameter is taken in from a for loop, We need to find the maximum and minimum of all numbers within this range. It is simply a way to find the values more efficiently since they must be one of those values so simply assign the first one. Your for loop that finds the minimum should be after the while loop that reads the input, not inside it (since currently it goes over un-initialized elements of the array, so it always finds a 0 as the minimum). Finding largest number in Java. 0" to "92. So finding max and min can be accomplished as follows, using Comparator. The program I am looking to create would see all the local minimums and maximums for a function which oscillates around the x-axis (This is not a school assignment, although I have mentioned cos(x) in the outline below). Example 4: Using a For Loop with ifelse Function Here is naive way of finding find minimum and maximum value in an unsorted list where we check against all values present in the list and maintain minimum & maximum value found so far. 0; while (infile. 5,4. In java there is no any built-in functions for finding minimum and maximum values of an array, You're initializing the values for smallest and largest to the first element in your array before you've added the values to it, so they're both set to the array's initial values of 0. The original few lines does not make much sense, because minDistance < distance would never evaluates to true since you just set minDistance = distance; distance = calculateHotSpot(point1, point2); . Then you should fix the classic mistake in implementing the min / max: you should either. MIN_VALUE to find min and max value in an array below is a code snippet of finding the largest and smallest value from a loop. The conversion of the array to a list has a constant time complexity of O(1), and finding the minimum and maximum values involves iterating Because of the way you choose the random values in a, there will be no value less than zero - but there is also no guarantee that any of the values will be exactly zero. min(min, 4); min = Math. You should create two double variables called maxVal and minVal. So maximum = 20 and minimum = 20. It then iterates over the elements of the array using a for loop and updates the values of max and min if the current Declare 2 variables, min_element and max_element, to store the minimum and maximum elements, respectively. It's an initialization trick, in case the list is empty, it will return infinite, meaning with that that the Explanation on Integer. All the elements are further compared through Finding the Maximum and Minimum value in python using loops. Hi I'm having a problem to write a loop which finds the largest value. } std::cout << "Smallest: " << min << "\n"; In Java you can find maximum or minimum value in a numeric array by looping through the array. To return the maximum element of the given collection, we can use the max() method, and to return the minimum value, we can use the min() method of the Collections class from the java. This way we know exactly which is the first statement to assign to smallest, and as others have stated previously get rid of the else block for if statement within the for loop. Use Case: Perfect for those who need a straightforward solution with no additional memory overhead. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Why do we initially set min and max to the first value in the array when trying to find the minimum and maximum value? You don't have to set min and max to the first value. Java Program to find the minimum element of an array 2. Algorithm. int min = 0; int max = 0; for (int i: list){ //find max and min here } return max - min + 1; I am looking for a way of calculating the minimum and maximum values for a function in Java. max(); mapToInt is the key function that describes how to convert the input to an integer type. Is there a metho The key points to solving this problem are to maintain state for the minimum and maximum values seen which is defined outside the loop. iterator(); Entry min, max; // Assumes that the list is not empty // (in which case min and max aren't defined anyway). max() spell "accumulator" correctly; remove all variables you are not using (cnt) Try this: No, it's seriously not worth changing. int minMax = 0; int smallest = 0; int largest = 0; for(int i = 1; i <= totalNumbers; i++){ System. Then in the second for loop we check every value in the array if it is maximal (so checking the first value against a load of zeros) then you exit the nested for loop and print the statement (with the value of a[0], if it was positive). You don't want to compare using strings but by the natural order of your double elements, i. For example: // While there is still stuff in the This summary includes the min and max but also provides the average, sum, and count of elements in the Stream. At the end of the loops just print the last highest palindrom and its i and j values. 1 @Mumfordwiz - The array that's returned is the maximum red value, the maximum green value, and the maximum blue value. Java Program to find the maximum element of an array. Find highest,lowest and average in a loop. so my homework question is prompt user a series of integers and find the max and min of those integer. MIN_VALUE. Create two variables ’max’ and ’min’ to hold the maximum and minimum values . It's trivial to write a function to determine the min/max value in an array, such as: /** * * @param chars * @return the max value in the array of chars */ private static int maxValue(char[] A straightforward solution: def minimum(lst): n = float('+inf') for num in lst: if num < n: n = num return n Explanation: first, you initialize n (the minimum number) to a very large value, in such a way that any other number will be smaller than it - for example, the infinite value. MAX_VALUE and max at Integer. Then for the other readings, compare the reading to the current maximum and minimum and update the maximum and minimum accordingly. Just be sure to initialize your min/max variables properly (Double. Code: Given an array, write functions to find the minimum and maximum elements in it. Java Minimum and Maximum values in Array. I have literately tried everything from writing separate methods and so on and still the output in 0. This is obviously a "Learn Java" class, not an algorithms class. MIN_VALUE and lowest = Integer. Definitely it will be the minimum of all the numbers provided. min(min, 9); min = Math. collector()) fooStream. If you found a palindrom compare it to the last highest palindrom. max(double a, double b) and Math. (Though the bands might be in a different order depending on the library you're using In python there are many ways to get minimum and maximum from a list by using different method such as using min() and max() function, by using “for” loop, and by using sort()function. MIN_VALUE returns the largest and smallest number that is representable by an Integer value. It then iterates over the elements of the array using a for loop and updates the values of max and min if the current element is greater than max or smaller than min, respectively. min(min, element); } Share. min(double a, double b) should come in handy. I think that once you go into the while loop you will never get the new min/max/avg calculated. In the Comparison in Pairs method, we'll implement the following steps. How can i get the min value in the simplest possible way // randomStream(n, min, max): e. The minimum loop seems to be correct as you have it IF you initialized the min variable outside the for loop. Approach 1: Scanner input = new Scanner(System. One common task is finding the maximum and minimum values in a list or collection. And then, what you are doing is to always get the minimum of two values, so this can be simplified by using the Math. So if your numbers are all negative, you'll get a highest of 0, incorrectly. // if it is smaller than update your guess. The algorithm to find the maximum and minimum node is given below. Java cannot easily return two values from a method. MIN_VALUE' and loop alone will take care of everything. This I want to find the maximum and minimum value by the for loop, but problem is that when array value is start from a maximum number like (100,30,50,60) then output is the correct first maximum value then, minimum value. min(min, 6); // min = 4 Within the loop, update the max_value by comparing the current element value with the existing max_value. Using Math. MAX_VALUE; In fact, you don't need the array at all, since you don't use it after the loop. Trying to find the minimum is the problem. 4,NA,NA,NA} so Ignore a By initializing the min/max values to their extreme opposite, you avoid any edge cases of values in the input: Either one of min/max is in fact one of those values (in the case where the input consists of only one of those values), or the correct min/max will be found. max() functions to determine the minimum and maximum values. I searched this but did not find it. // Then the Math. Hint : In this loop, find the max and the min value. getting stuck on For a start you can use Math. naturalOrder() instead of Comparator. max(arrayList); We will maintain two variables min and max. Collections (Documentation) Find a maximum and minimum value using for loop. Introduction Java 8 introduced lambda expressions and the Stream API, enabling developers to perform operations on collections more efficiently and concisely. In your loop, as you are getting each double value, use Math. Share. However, a recursive solution will require less comparisons than naive algorithm, if you want to get min, max simultaneously (it isn't necessarily faster due to function call overhead). – Kevin Anderson. max(minimum of and b,c) gives // the minimum value of a,b,c int min=Math. // Now check if the guess is correct and update if you are wrong. MAX_VALUE int max = Integer. Each value is called an element specified by a First, you need to move min and max variables out of the loop. Create a class Node which has two attributes: data and next. Next step would be to iterate over your set of values and check whether a value is below current minimum, and if so set minimum to that value. 2. 0") you get the result you see. The else block is causing what OP I want to input 10 marks for subjects from user. Instead, in you add method, you need to be comparing the values as they are added, you can use Math. Here is the code to do that. Here is what I have: public int greatestNegative(int[] list) { for (int i = 0; i < and initialize minDistance to Double. But here you have function |x|=abs(x), which uses 'if' inside. (The only default values that wouldn't cause problems are smallest = Integer. This can be easily be done using nested loops. The resulting stream then has additional aggregators and collectors specific to integer types, one of the being max(). MAX_VALUE. 0" The line largest = array[i]; does NOT mean 0 = array[i] as you believe. for(int loop = 0; loop < 5; ++loop) { // check if data[loop] is smaller than your current guess. Java: find the largest number in a list of I am trying to find the Minimum and Maximum Value in an ArrayList without Sorting: Here is my Current Attempt - However I cannot seem to be getting it to work properly: import java. length; j++){ In a basic java program, I've defined two methods of a class that are supposed to return the maximum and minimum numbers from a set of four doubles. min and Math. Lets say that you want to add the names of some student and you also want to save the corresponding marks obtained by each student. Get Array Elements and Print Cubic Values in Java; Find the Maximum and Minimum Element in an Array in Java; Get Array Elements and Print all Odd Numbers in Java; Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Arrays concepts Java: 1. Then here the solution to find the maximum product triplet in C with explanations in comments - The naive algorithm is too loop and update min, max. @AndySenn using Java is one such piece of overhead. I have looked after similar problems here in stack-overflow and I still can't make it work. collector(fooComparator)) Write a java program to find maximum and minimum value in array. In your first loop, when you are computing min/max, you should initialize both min and max to the first value of the array. comparing(String::valueOf). min() the methods that find only maximum and minimum of 2 numbers. After reading a lot, I decided to test the "top 3" solutions myself: discrete solution: a FOR loop to check every element of the array against the current max and/or min value; I am working on this program to find minium and maximum values of the variable milesTracker and have been successful for a few tests but it breaks testing it with values {{-5}, {-93}, {-259}}. Comparing via strings will result in the characters being compared and since the character value of 9 (of "9. For both ’max’ and ’min’, we will pass one You can't know what the max or min is until after the loop has completed, so you can't print either before that. How to find "max" 0. C I'm trying to get each color's max and min value. You should declare a max variable and initialize it with some very low value. 1. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Your question is not that much explanatory. This is a terrible idea because, as you have realised, you have to iterate over the entire map and use String. quick sort) to do that job easily. in temperatures total = total + value if value > max max = value else if value < min min = value print "Minimum: " min In traditional way, I would have to sort the map according to the values, and take the first/last one. Then it returns the number of values, the min/max, and average value. length: Sort data[i] Check if the first value of data[i] is less than the minimum and change it if it is. mapToInt(Integer::intValue Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Then just iterate through the list, comparing each element to the current minimum and maximum elements: Comparator<Entry> comparator = new EntryComparator(); Iterator<Entry> it = list. You code works for max only by accident :) Try entering only negative values to the input and your max will also give only 0. nextInt(); maximum = Math. Start min at Integer. If the size of the array is odd, then we'll initialize the minimum and maximum values to the first element of the array. in); int maximum = Integer. max() In this approach, a loop is used in combination with Math. Otherwise output first minimum value, then maximum value. Assuming that what you are trying to do is find the largest and smallest integers are in an array of integers: max value of iterator in for loop in java. MAX_VALUE, so it will be Use the for loop to write a program to prompt the user to enter twelve n amount of numbers and then display the minimum, maximum, sum and the average of these numbers. max( next, maximum); minimum = Math. I need to find the maximum values within an array and minimum values. but instead of doing so directly it's cleaner in my opinion to track the indices of the min and max elements. As it stands, if the first value you enter is also the maximum, the results will be incorrect: It will be less than Integer. minimum of list to maximum of value in Javascript. This It initializes max and min variables to the first element of the array. For example Double. Find min and max value of array. MAX_VALUE, evens=0, odds=0; double average=0. None of the values are smaller than 0, so smallest remains 0. max() and Math. Math. Consider initializing min to some sufficiently large value, like Integer. print("Number " + i The initial value of the maximum should be Integer. MIN_VALUE is a regular double, I don't see the need for the Double type. ; If the size There is a O(n) solution if you find the 3 maximum and 2 minimum values in linear times. (average, possible update of the maximum, resetting the variables, etc. max(max, valueYouWantToCompare); Finding the correct Java syntax is your task now :-) Good luck! This uses list comprehension to create a new array of all the indices at which the minimum number occurs. and I can't seem to get how to use this – Mumfordwiz. You can use Collections API to find it. MIN_VALUE and the initial value of the minimum should be Integer. I added variables to track the indices of the min and max. If it is higher than the saved value store the new value as last highest palindrom. Collections. MIN_VALUE and smallest number are initialized with Integer. util package. In Java you can find maximum or minimum value in a numeric array by looping through the array. Use a loop to iterate over the array, starting from In this approach, a loop is used in combination with Math. The Math. comparing. It is highly recommendable to split the computational part from the input/output. It is supposed to take the Math. input = 3, then 3 random numbers like 3, 5, 7. doubl I've got a homework assignment where I need to write a program using a loop that takes 10 integer values from a user and outputs the minimum of all values entered. public static int maxValue(int values) { int maximum = Integer. In the first for loop we assign the first int to a[0]. So, you see the print statement for as Java Minimum and Maximum values in Array – Karl Knechtel. Without adding those value into array is there any efficient java code for get the maximum value from that five value set. The english version of the question asking to find the max mark for each subject/module. max() after converting the array to a list is O(n), where n is the number of elements in the array. max(max, element); min = Math. MAX_VALUE). Because this is an int array the values are initialized to 0. mozway mozway. 258k Integer. def max_min(iterable, key=None): ''' returns a tuple of the A user should input a number "x", and then the count of "x" numbers, e. You never calculate the max and the min value in your loop. To print the minimum and maximum number in an array, user has to create an array with integers. Then calculate the range and return it. How to find the min / max value using for-loop. If your numbers are all positive, you'll get a lowest of 0, incorrectly. If you are giving only positive numbers to your program,min value will stay 0 If you want to find min and max value of array you can initialize min and max like this: int min = Integer. utils. max() to compare the current double value to maxVal and minVal. and want print total max min average I found total,max & average using this code import java. ) You also need the outer loop (in the stated code, these calculations are done for one student only) which you would control in a different manner. stream(). How to fix it. you set min and max on 0 and then, in for loop, you check if it is less than 0. Typically you'd then start the loop counter from 1, since the 0th value is already dealt with: for(int j=1; j<array[i]. Afterwards the program should give an output of the average, min and max value of this "x" numbers. println("Please enter number"); numbers[i] = input. It can all be in the loop. Input : list = [10, 400, 3, 2, 1, -1] Output : max = 400, min = -1. Min will hold minimum value node, and max will hold maximum value node. I want to calculate max and min of five inputs from the user, i managed to get max value but failed to get the min value instead i am getting 0 as my min value which was initialized from before in class Compare. hasNext()) I've written the code for the listed variables within the while loop but I can't figure out what to do about the largest and smallest value. max. These are very I am trying to take 10 integers from the user's input and find the minimum value using a for loop. This appears to be correct. So I worked on this for a bit and I think I have something close to what you're looking for using a do while loop. Getting min and max values from an array - Java. MIN_VALUE; int minimum = Integer. I suggest Integer. Also, you might use Math. Make a separate assignment to smallest altogether before the loop begins. println("Maximum number "+max); use a for loop instead of a while loop (you need intialization, condition and iteration) use the JDK's API more - Math. Commented Jan 14, 2014 at 16:30. MIN_VALUE, or; Start both min and max at the first value entered. 0") is greater than 1 (of "16. hasNextInt(); i++ ) { int next = scan. Improve this answer (0,len(student_scores)): if student_scores[n]<=min: min=student_scores[n] print(min) # using for loop to go through all items in the list and assign the smallest value to a I need to return the greatest negative value, and if there are no negative values, I need to return zero. Just assign the scanner result to an int variable, declared inside the loop. Output : max = 20, min = 1. collect(Stats. Because you're starting at a very high value already, there's only one value that's higher than it in the entire array. MAX_VALUE; private int Collection<Integer> values = new ArrayList<>(); OptionalInt max = values. Initialize smallest and largest to a valid int from your list of numbers - initializing them to 0 is going to result in smallest equaling 0 when you're finished. Even the method call cost will be removed if the min function is called enough. //Find maximum (largest) value in array using loop System. For one of the questions i was asked to solve, I found the max value of an array using a for loop, so i tried to find it using recursion and this is what I came up with: Firstly you need to understand a lot of thing with you code is wrong. So far I have the average and sum of squares portion, but the minimum and maximum is biting me. private int smallest = Integer. Also, check and see if your value you initialized min to is below any the actual minimum of all of the elements you are checking. Finding Max value in This would be my preference for making the first assignment to smallest variable. This is my solution using static methods max and min from class Math: Find highest number using if statement in a for loop java. Suppose you have a key that depends on an Integer k and a String s. min() and Collections. What is an Array? In JavaScript, an array is an ordered list of values. It should be noted that primitive types must have a value. MAX_VALUE and I think you'll find it This is a interview question: given an array of integers find the max. e. You have values larger than that, so largest works. The sort of improvements you're going to get when fiddling with micro-optimisations like this will not be worth it. We'll need a Stats class to hold count, min, max, and factory methods to creat stats collector. for(int ii = 1, j = 0; j <= copySel ; ii++, j++) { //btw, what is 'j' for? attempt I am trying to resolve an excercise about finding out the lowest value in array using loop. After the loop completes, print the final max_value, which holds the maximum value found in the vector. max(x,y) returns the maximum of x and y. The program works fine for other methods, but it displays maximum value for both max and min. MAX_VALUE; largest = Integer. you may adjust it with your requirement. The average is sum / count. [GFGTABS] C++ // C++ code for the ap is initializing the maximum value on the ith row to the first value in that row, than scanning the row to find any larger and increase max accordingly. min(Math. But as Jeremy said fix your indentation :) – Quantico. Min & Max results of a for loop in java. I cannot, however tell you how to calculate average min and max WITH arrays. First of all, you can implement function sort(a, b), which returns pair of sorted values. This code accepts user input first, then checks it's value in comparison to the last input and return either "Input a higher value", "Duplicate number found", or it sets the last number entered to the current number. If you do that, you should also change the for loop to only iterate over the elements you assigned to the array (indices 0 to count-1), and not the entire array. In the above example, 1 will be minimum value node and 8 will be maximum value node. Java 8 Stream min and max method example : Introduction : In this tutorial, we will learn how to use min and max methods of Java 8 Stream to find the minimum and maximum element in a list. MAX_VALUE: double minDistance = Double. out. However, you initialize m to be zero, since that is the default value of the array elements; nothing can be smaller than this, so the answer is always zero. Auxilary Space: is O(1), as we are not using any extra space. min The time complexity of finding the minimum and maximum values using Collections. Your max seems to work. . public Finding the maximum and minimum values of a List using the max() and min() methods from the Collections class. MIN_VALUE; for(int x : values) maximum = (x > maximum) ? x : maximum; return maximum; } Loop to find max value. No loop required, use max method from java. MIN_VALUE OK, I have been at it for a long time now. Initialize max to be the smallest Integer possible; Using the for-each loop check if the current element is larger than max and if so make that the new value of max; Return max after the for-each loop is finished ; Personally I would create a separate method for this: max = 0 min = 0 set up array of a[24] loop start if a[x] > max max = a[x] else if a[x] < min min = a[x] print Max temp: print Min temp: I would like to see how you guys would construct a clear pseudocode of this program. The, for each element of the array you do the following: Single Loop Trick/Comparison in Pairs. println("Maximum Value = " + You have to initialize 'min' value outside the loop, and you must initialize 'min' to large value, something like 'Integer. min() and Math. Changing "16. min(a,b) gives minimum of a,b // Then the Math. max(Math. max(maximum of a and b,c) gives // the maximum value of a,b,c int max=Math. In particular, the minimum value should be seeded with the maximum possible integer value, and the In this article, we will discuss different ways to find the maximum and minimum elements of the array in C. I'm a newbie in java. min(a,b),c); // Print them System. Improve this answer. max to make the comparison easier, for example. So the solution is a one-liner, and you can either obtain the entry or the key Your highest and lowest variables both start at 0. MIN_VALUE or Double. If you have a problem with your algorithm, your best bet is to look into macro-optimisations ("big picture" stuff like algorithm selection or tuning) Since Double. MAX_VALUE; for( int i=0; i<10 && scan. In Java 8, Collections have been enhanced by using lambda. I have implemented a for-loop to find the max value just not sure how to isolate to each column. min(x,y) returns the minimum of x and y. using minimum comparisons. MIN_VALUE; int min = Integer. Maximum and Minimum using loops. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company I was asked to write a program to find the minimum, maximum, average and sum of user inputs and I came up with the following program but there seems to be a problem with the loop I'm using because the program just exits when compiled. When I test out my code with "5 16" the output is [6, 7]. Map<String, Object> where the keys are k + " " + s (or something similar). – Scott Hunter. The first method can be applied to the entrySet of the map, and the second one provides a Comparator that compares map Entry objects by their value. Hot Network Questions Is there a way to find out the Maximum and minimum of an array consisting of integer, floating point number and string or characters? in java for example: A={1,2,3,4,4. min method. First of all we need an array. Then in every iteration of the loop you could update your maximum like this: max = Math. findMin is also now called only once, not for every iteration in the loop, which is a little cleaner (and slightly faster). While summaryStatistics() offers a convenient way to find both the min and max, the Stream API also I would traverse all the rows I have and set the values in these arrays with the maximum and minimum values of each row. To do it you can use following idea: min(a, b) = (a+b)/2 - |a-b|/2 and max(a, b) = (a+b)/2 + |a-b|/2. MAX_VALUE'. If you are I was wondering while using java. For an array of string i wil So I'm coding in C, and I need to come up with code that will take n numbers from the user, and find their minimum, maximum, average, and sum of squares for for their values. Also, if you need to use only 4 There was some confusion as to if the findMin method returned the minimum value, or the minimum index. Here, we have given a list of numbers and we have to find the smallest number in given list by using different methods, such as min(), for loop(), and sort(). Scanner infile = new Scanner ( new FileReader(args[0]) ); int count=0,sum=0, largest=Integer. Because you're starting at a very high value already, there are several values that are lower than it in the entire array. This program handles both positive and negative numbers, hence the largest value is initialized with Integer. Comparator. You have not read any values at this point, so initialize your min and max values with: int max = Integer. Just set min initially to Integer. print out max and min numbers of the input. int min = arr [ 0 ]; int max = arr [ 0 ]; for ( int num : arr ) { min = Math . min( next, minimum); Given an unsorted list of integers, find maximum and minimum values in it. Find max values from a array Let's see how to obtain min, max values by using a single funtion. Entry#comparingByValue method. Commented Oct 9, 2015 at 17:12. I need to write a program that reads in an arbitrary number of data points from standard input. // when you have checked all the values exit the loop. Commented Feb 8, 2022 at 15:20. max(a,b),c); // Math. length]; //Array to store the result for(int Not sure where to begin honestly, I was able to find average using the user's input but can't seem to figure out the largest number or the smallest number from the numbers entered. thanks. Number of Comparisons: The number of comparisons made to find the minimum and maximum elements is equal to the number of comparisons made during the sorting process. in); int[] numbers = new int[10]; for (int i = 0; i < numbers. So, you only see the code enter the if block once and print only once. MAX_VALUE and Double. Java Program to find largest and smallest of N numbers without arrays Here is our sample program to find the smallest and largest of N integers without using an array. min ( min , num ); Three ways to find minimum and maximum values in a Java array of primitive types. No, you wouldn't. 1 Enter an input value: 8 Enter an input value: 3 The maximum is: 23 The minimum is: 1 Share. I want to some help. Then the elements are read using the scanner class. You initialize min to 0, and no number you input is ever going to be less than 0 (assuming you're only entering positive numbers), so min will always be 0. and min. Hot Network Questions How plausible is Comparator. maxValue = inputArray[i]; } } return maxValue; } // Method for getting the minimum value And use that value as your maximum and also minimum. Hot I had the same problem, I needed to obtain the minimum and maximum values of an array and, to my surprise, there were no built-in functions for arrays. java- find minimum/maximum in an entered set of numbers. In this rental program I need to display the user with maximum and minimum rents. length; i++) { System. int max = Integer. int[][] test = {{3, 9, 3, 5}, {4, 19, 4, 9}, {2, 10, 5, 6}}; I want to find the max value in each row in a two- I want to find the max value in each row in a two-dimensional array, and I wonder how to code it. Please Don't forget to Subscribe(c) Backgrou How do I get the max and min values from a set of numbers entered? 0. Finding the largest Number. Hot Network Questions Consequences of the false assumption about the existence of a population distribution in the statistical inference, when working with real-world data I am trying to find the max value in each column of a 2d array in Java. You would have to iterate through all values and at each step compare the current element with the smallest one seen so far. I am struggling to correctly write the if statement. If this is a frequently needed feature, we better make a Collector to do the job. How would I determine the I'll simplify this a bit. Whichever value is greater becomes the new max_value. The code used to find all occurrences of the minimum value element can be found here. Commented Oct 8, 2022 at 8:37. MAX_VALUE and then the first iteration will end up with the correct highest and lowest value. length ; i++) // Need to In this video I will show you how to find the highest and lowest number among all the inputs using Java Netbeans. ; I prefer the second approach, because it keeps explicit initialization out of the code: ahhhhh, i understand now, every time 1 loop finishes, max has new value and depending on whether it's bigger/smaller and the arrow direction it will change – Jakub Mazurkiewicz. Time complexity: O(n log n), where n is the number of elements in the array, as we are using a sorting algorithm. Sorting. Obviously, I can loop over the array twice and use ~2n comparisons in the worst case but I Using simple for loop. getting stuck on if there's only one input. Stats<String> stats = stringStream. MAX_VALUE; for (int element : a) { max = Math. Scanner; class Example{ public static void You just throw away Min/Max values: // get biggest number getMaxValue(array); // <- getMaxValue returns value, which is ignored // get smallest number getMinValue(array); // <- getMinValue returns value, which is ignored as well Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company @user2994377 In additon to Christian's answer, there is another more subtle bug in your code. MAX_VALUE; min = Math. Scanner scan=new Scanner(System. mapToInt((x) -> x). So, that value at 0th position will min and value at nth position will be max. util. Then you can use a second loop to skip those elements when you copy nums to the new array. MIN_VALUE,smallest=Integer. MAX_VALUE to make sure that negative values are handled. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Doing a project for AP Computer science, and I still haven't managed to figure out how to do this part: The program is supposed to ask the user for 5 test score inputs and then the code will "curve" the smallest value entered by taking the square root of the score and adding the integer value of the square root to the original score. If you want to use a loop, then loop with the current max value and check if each element is larger, and if so, assign to the current max. The simplest method to find the maximum and minimum element of the array is iterates through the array and compare each element with the assumed minimum and maximum and update them if the current element is smaller or larger respectively. It now returns the minimum index. The keys for a concise, efficient and elegant solution here are the Collections#min method and the Map. I get the five double data type values from five different function. The most simplest way to find min and max value of an element is to use inbuilt function sort() in java. Like, //Find maximum Math. finding the second largest value in an array using java. It might seem a good idea to use a . Anyway, I will tell you how you can find some elements without a loop: To get the max value of an ArrayList you don't need a for. The excercise is about generics. An example getting a min number without a loop would be: long min = Integer. Iterate through If you have an array, minimum is often calculated by first setting the initial minimum value to a known maximum value "infinity" or in this case 100. double max = m[0][0]; double min = m[0][0]; //declare variables to track the indices of the min and max int maxIndex1 = -1; int maxIndex2 = -1; int minIndex1 = -1; int minIndex2 = -1; . But you can also use nlog(n) sorting (i. Keep in mind I'm at a very rudimentary level, and I have not reached arrays In the case that you only want to go through your iterable once, (say it's an expensive operation to do, and really that's the only reason you should do this, instead of doing max or min separately, but that said, the below is a performance improvement on calling both separately, see numbers below):. You should initialize your m = a[0][0] immediately Basic syntax: Some may find it less elegant than newer Java methods. any idea? //Number serial. Store the according i and j values also. MAX_VALUE and Integer. let us calculate those values we're after: Calculating the sum is easy: min and max in java. Using java write two methods min and max to find maximum value and minimum value in linked list but the input list is array of integers Hot Network Questions Sous vide pouches puffed up - Is this product contaminated? See the below modification. I'm trying to find minimum maximum element in array and then delete the minimum and maximum. writing java code to find max&min. *; class Using Java 8 you can do this very easily traversing the list only once: IntSummaryStatistics stats = al. Then all you need is to save minimum value from the last turn and compare it with input in the next one. However, with a simple trick, we can get the maximum of as many numbers as we In this example we are finding out the maximum and minimum values from an int array. Traditionally, this required iterating over the collection manually, but with the Stream API, you can achieve this in a Let's go through the process. largest is a variable, so each time you get to the line largest = array[i]; you are changing the value of largest to be the current array[i]. In this tutorial, We traverse an array using for loop to find maximum and minimum value of a How To Find Minimum And Maximum Value In An Array Using JavaScript In this challenge you are going to learn how you can get the maximum and the minimum value of an array using JavaScript. min & Math. 4. .
