Fill an Array of Characters from User Input in Java

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
