Program for Sum of Digits of a Number in Java

Program for Sum of Digits of a Number in Java, there are following step perform:-

Create the object of scanner class and System.in to receive user input.
The nextInt() method scans the next token of the input data as an “int”.
Now initialize an integer number.
Make one while loop to check number is not equal to zero.
Find the remainder by using the modulo (%) operator. It gives the last digit of the number.
In if condition to check reminder is equals to zero otherwise goes to else condition.
Declare a variable sum to store the sum of numbers and initialize it to 0.
Add the last digit to the variable sum.
Divide the number by 10. It removes the last digit of the number.

				
					import java.util.Scanner;

public class SumOfNumber {
	public static void main(String[] args) {
		System.out.println("Enter the digit number:");
		Scanner sc = new Scanner(System.in);
		int num = sc.nextInt();
		int digit = 0;
		int sum = 0;
		while (num != 0) {
			digit = num % 10;
			if (digit % 2 == 0) {
				sum = sum + digit;
			} else {
				sum = sum + digit;
			}
			num = num / 10;
		}
		sc.close();
		System.out.println("sum of digit is - " + sum);
	}
}

output :-
Enter the digit number: 257
sum of digit is – 14
