Answer 1

Answer:

import java.util.Scanner;

public class Main {

 public static void main(String[] args) {

   double total = 0;

   double fPrice, sPrice, tPrice;

   int firstN = 0, secdN = 0, thirdN = 0, fTime, sTime, tTime;

   int totalT = 0;

   isEnd = "n";

   for (;;){

       if (isEnd == "y"){

           break;

       }

       Scanner in = new Scanner(System.in);

       int option = in.nextInt();

       switch (option){

         case 1:

             fPrice = 2.50;

             fTime = 5;

             System.out.print("Enter number of items: ");

             firstN += in.nextInt();

             totalT += fTime * firstN;

             total += fPrice * firstN;

             break,

         case 2:

             sPrice = 3.75;

             sTime = 7;

             System.out.print("Enter number of items: ");

             secdN += in.nextInt();

             totalT += sTime * secdN;

             total += sPrice * secdN;

             break,

         case 3:

             tPrice = 5.99;

             tTime = 12;

             System.out.print("Enter number of items: ");

             thirdN += in.nextInt();

             totalT += tTime * thirdN ;

             total += tPrice * thirdN;

             break,

        default:

             System.out.println("Looking forward to the Weekend");

       }

       System.out.print("Do you want to end the order? y/n: ");

       isEnd = in.nextLine();

   }

   System.out.println("Number of Type 1 candles bought : "+firstN);

   System.out.println("Number of Type 2 candles bought : "+secdN);

   System.out.println("Number of Type 3 candles bought : "+thirdN);

   System.out.println("Total cost is : "+total);

   System.out.println("Total burn time is : "+totalT);

   double costPerBurn = (totatT * 60) / total;

   System.out.println("Cost per minute : "+ costPerBurn);

 }

}

Explanation:

The Java program creates a continuous for-loop statement that gets the candle type, price and amount ordered from a switch and accumulates the total cost and burn time of the candles bought and the cost per minute burn of the candles consecutively.
