Sum of Digits Program in Java

This is a Java Program to Compute the Sum of Digits in a given Integer.

Enter any integer number as input. After that we use modulus and division operation respectively to find the sum of digits of number as output.

Here is the source code of the Java Program to Compute the Sum of Digits in a given Integer. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

```
import java.util.Scanner;
```
```
public class Digit_Sum 
```
```
{
```

    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);

```
    }
```
```
}
```

Output:

$ javac Digit_Sum.java
$ java Digit_Sum
 
Enter the number:456
Sum of Digits:15
