How to sum digits of an integer in java?

Question

I want to write a program which takes numbers and finds the sum of digits using the % remainder symbol. 

Let say:

Number = 123

Expected output = 1+2+3 = 6. 

Can anyone help me with how to find the sum of digits of a number?

Answer 1

Here‘s the solution to your question:

public static void main(String[] args) {

        int inputNumber = 321;

        int result = 0;

        while (inputNumber > 0) {

            result = result + inputNumber % 10;

            inputNumber = inputNumber / 10;

        }

        System.out.println(result); 

}

Output: 6
