 5. Write a Java program to calculate sum of digits of a number.

import java.util. *;

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

Enter Digits:
12345
Sum of Digits: 15
