Java Recursion Program Practise 5 - to input a number and print the sum of digits of the number

Java Program to input a number and print the sum of digits of the number using Recursive Function

import java.util.*;

class Main {

   int digit(int n){

       if(n==0)

       return 0;

       else

       return (n%10+digit(n/10));

   }

    public static void main(String[] args) {

        Scanner in = new Scanner(System.in);

        int a;

        System.out.println("Enter the number whose sum of digit is desired using Recursive function");

        a = in.nextInt();

        Main ob = new Main();

        System.out.println(ob.digit(a));

        

        

    }

}
