Java Program to fill an array of characters from user input

For user input, use the Scanner class with System.in. After getting the input, convert it to character array −

char[] a = s.next().toCharArray();

Now, display it until the length of the character array i.e. number of elements input by the user −

for (int i = 0; i < a.length; i++) {    System.out.println(a[i]); }

To fill an array of characters from user input, use Scanner class.

Example

import java.util.Scanner; public class Demo {    public static void main(String args[]) {       Scanner s = new Scanner(System.in);       System.out.println("First add some characters...");       char[] a = s.next().toCharArray();       System.out.println("Elements = ");       for (int i = 0; i < a.length; i++)          System.out.println(a[i]);    } }

Now, enter some input −

RSTUVWXYZ

After entering, you need to run the program to get the following output −

Output

First add some characters... Elements entered = R S T U V W X Y Z
