Apr 17, 2025 · We can use the Scanner class with loops to take input for individual array elements (to use this technique, we must know the length of the array). In this example, we will understand how to take input for a two-dimensional array using the Scanner class and loops.

Jan 18, 2016 · I was wondering how to load up an array (with user input) using a while loop. The code below prints a 0. Scanner scan = new Scanner(System.in); int i = 0; int n = 0; int[] myArray = new int[10]; System.out.printf("enter a value>>"); while (scan.nextInt() > 0) { for (i = 0; i > 0; i++) { myArray[i] = scan.nextInt();

Loop Through an Array. You can loop through the array elements with the for loop, and use the length property to specify how many times the loop should run. The following example outputs all elements in the cars array:

To take input of an array, we must ask the user about the length of the array. After that, we use a Java for loop to take the input from the user and the same for loop is also used for retrieving the elements from the array.

To put input from a Scanner into an array in Java, you can use a loop to read the input and store it in the array. Here is an example of how you can do this: public class Main { public static void main(String[] args) { Scanner scanner = new Scanner (System.in); // Read the size of the array . System.out.print("Enter the size of the array: ");

Dec 23, 2012 · First: use a List instead of an array for user input. Just .add() your inputs to it. But see below for a better solution, ie using a Set. Second: String has a .trim() method which removes whitespaces both at the beginning and end, use that and test …

This tutorial will guide you through the process of using the Java Scanner class to collect user input and store it in an array. We will cover everything from basic setup to more advanced techniques, making this guide suitable for beginners and …

Mar 11, 2025 · In this tutorial, we’ve explored how to implement a while loop in Java that continuously requests user input. We covered basic input handling, input validation, and even created a simple menu-driven program.

Apr 22, 2025 · Simply add the required element in the list using add () method. Convert the list to an array using toArray () method and return the new array. Example: This example demonstrates how to add element to an array using an ArrayList.

Apr 23, 2024 · 1 - You can take array input in Java by first specifying the size of the array. 2) You can then create an array of that size using the ‘new’ keyword. 3) After creating the array, you can use a for loop to iterate through each element and take input from the user for each element.
