Question

Program#3(17 points): write a java program (SunDigits) as follows The main method prompts the user to enter an integer number. The method then calls Method Sum (defined blew) to add the digits and return their total. The main method then prints the digits total with proper label as shown below Method Sum )is of type integer and takes an integer value. The method recursively adds up the digits and returns their total. Document your code and use proper prompts for inputs and format outputs as shown below Entered integer 123456 Digits sum: 21 Digits sum: 6 Entered integer 55555 Digits sum: 25 Entered integer 1010101010 Digits sum:

Answer 1

Java Code for the question:

import java.util.Scanner;

public class Base1 {

      static int sum =0;

      public static void main(String[] args) {

            //Scanner function that gets the input from User

            Scanner scan = new Scanner(System.in);

            System.out.print("Enter an Integer: ");

            int number= scan.nextInt();

            //Calling the recursive method to sum the digits

            int total = sum(number);

            //Printing out the results

            System.out.println("Entered Integer: "+number);

            System.out.println("Digits Sum: "+total);

      }

      //Sum method that adds the digits of the given integer

      private static int sum(int x) {

            // TODO Auto-generated method stub

            sum = x%10;

            if(x==0){

                  return 0;

            }

            else{

                  return sum + sum(x/10);

            }

           

      }

}

Output:

<terminated» Base1 [Java Application] C Digits Sum: 6
