Java Program to fill an array of characters from user input

Java 8Object Oriented ProgrammingProgramming

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
