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
