In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.Scanner;
public class Javaexcercise 
{
    public static void main(String args[])
    {
        int m, n, sum = 0;
        Scanner s = new Scanner(System.in);
        System.out.print("Enter the number:");
        m = s.nextInt();
        while(m > 0)
        {
            n = m % 10;
            sum = sum + n;
            m = m / 10;
        }
        System.out.println("Sum of Digits:"+sum);
    }
}

Result:

Enter the number:123456

Sum of Digits:21
