public class sumofdigit 
{
  public static void main(String[] args) {
    int n, sum = 0, m;
    System.out.println("Enter a number: ");
    Scanner sc = new Scanner(System.in);
    n = sc.nextInt();
    while (n > 0) {
      m = n % 10;
      sum = sum + m;
      n = n / 10;
    }
    System.out.println("Sum is= " + sum);
  }
}
