java very difficult programming

Write a program that reads an integer between 0 and

10000 and adds all the digits in the integer. For example, if an integer is 932, the

sum of all its digits is 14.

Description:

Use the % operator to extract digits, and use the / operator to remove the

extracted digit. For instance, 932 % 10 = 2 and 932 / 10 = 93.

Solution

import java.util.*;

public class Message {

 public static void main(String[] args) {

    Scanner in = new Scanner(System.in);

   int num,sum=0;

   System.out.println("Enter the mass in pound");

   num=in.nextInt();

   sum+=num%10;

   num/=10;

   sum+=num%10;

   num/=10;

   sum+=num%10;

   num/=10;

   sum+=num%10;

   num/=10;

   sum+=num%10;

   num/=10;

   System.out.println("The sum of all the element is ="+sum);

 

 }

}

Output:
