Introduction
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..
Write a Java program and compute the sum of the digits of an integer
import java.util.Scanner;
public class Javaexcercise {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter an integer: ");
long n = input.nextLong();
System.out.println("The sum of the digits is: " + sumDigits(n));
}
public static int sumDigits(long num) {
int sum = 0;
while (num != 0) {
sum += num % 10;
num /= 10;
}
return sum;
}
}Result
