Write a Java program that accepts an integer (n) and computes the value of n+nn+nnn

import java.util.Scanner;
public class Exercise44 {
 public static void main(String[] args) {

  int n;
  char s1, s2, s3;
  Scanner in = new Scanner(System.in);
  System.out.print("Input number: ");
  n = in .nextInt();
  System.out.printf("%d + %d%d  + %d%d%d\n", n, n, n, n, n, n);
 }
}

Sample Output:

Input number: 5                                                        
5 + 55  + 555
