Java program for sum of digits of number

In this post, we will see how to find sum of digits of number in java.
You can find unit’s place digit by number%10, add it to the total and divide the number by 10 to remove the unit’s place.

import java.util.Scanner;

public class DigitAdditionCalc
{
    public static void main(String args[])
    {
        int number, remdr=0, total=0, tempNum;
        Scanner scan = new Scanner(System.in);

        System.out.print("Enter a Number : ");
        number = scan.nextInt();

        tempNum = number;

        while(number>0)
        {
            remdr = number%10;
            total = total+remdr;
            number = number/10;
        }

        System.out.print("Sum of digits of number " +tempNum+ " is " +total);        
    }
}

Output:

That’s all about Java program to add digits of number.
