Input the order number and count the sum of products. if print -1 stop the execution.Ex: Input 1 2 4 5 -1 Output 26. Need to use switch

Answer 1

import java.util.Scanner;

public class SumOfProducts {

      public static void main(String[] args) {

            // TODO Auto-generated method stub

            //Scanner function to get the input from keyboard

            Scanner scan = new Scanner(System.in);

            //Asking the user to input order number

            System.out.print("Enter the order #: ");

            int total=0;

            int order=scan.nextInt();

            //Total is calculated if and only if the order is not -1

            while(order!=-1){

                  //Using Switch as per your requirement

                  switch (order){

                  //Calculating the Sum of products as per the input given by user

                  case 1: total = total+6; break;

                  case 2: total = total+8; break;

                  case 3: total = total+12; break;

                  case 4: total = total+3; break;

                  case 5: total = total+9; break;

                  // If User gives any number other than 1,2,3,4,5,-1 It is considered as invalid

                  default: System.out.println("Invald entry give again"); break;

                  }

                  System.out.print("Enter the order: ");

                  order = scan.nextInt();

            }

            //Printing the Sum of Products

            System.out.println("Sum of Products: "+total+"$");

      }

}

Output:

<terminated> SumOfProducts [Java Enter the order: Enter the order: Enter the order: 4 Enter the order: 5 Enter the order: -1 Sum of Products: 26
