Answer 1

Answer:

import java.util.Scanner;

public class CalculatingSales {

  public static void main(String[] args) {

      Scanner sc = new Scanner(System.in);

      int product, quantity;

      double total = 0;

      while(true) {

          System.out.println("Enter product_id and quantity(0 0 to stop): ");

          product = sc.nextInt();

          quantity = sc.nextInt();

          if(product==0 && quantity == 0)  

              break;

          switch (product) {

          case 1:

              total = total + 2.98*quantity;

              break;

          case 2:

              total = total + 4.50*quantity;

              break;

          case 3:

              total = total + 9.98*quantity;

              break;

          case 4:

              total = total + 4.49*quantity;

              break;

          case 5:

              total = total + 6.87*quantity;

              break;

          default:

              System.out.println("Invalid option");

          }

      }

      System.out.println("total value: "+total);

      sc.close();

  }

}

Explanation:

• Take the product and quantity as input from user.
• Use a switch statement to multiply the total with their relevant value.  
• Display the total value.
