Question

Write a java console application,. It simulates the vending machine and ask two questions. When you run your code, it will do following:

Computer output: What item you want?

User input: Soda

If user input is Soda

Computer output: How many cans do you want?

User input:            3

Computer output: Please pay $3.00.

END

The vending machine has 3 items for sale:

1. Soda the price is $1.50/can.

Computer should ask “How many cans do you want?”

2. Chips, the price is $1.20/bag.

Computer should ask “How many bags do you want?”

3. Juice, the price is $1.50/bar.

Computer should ask “How many bars do you want?”

When user type in different quantities, the computer should print out the total due amount.

The 2^nd one is the quantity of the items.

Solution code is given below with comments:

import java.util.*;

public class Main
{
   public static void main(String[] args) {
       // Scanner object for input from console.
       Scanner sc = new Scanner(System.in);
      
       // Setting price for the items.
       double sodaPricePerCan = 1.50;
       double chipsPricePerBag = 1.20;
       double juicePricePerBar = 1.50;
      
       // Takes input for the item user wants.
       System.out.println("What item you want?");
       String input = sc.nextLine();
       int quantity;
       double total;
      
       // Using equals method of String and then continuing with the
       // next question of How many items do you want
       if(input.equals("Soda")) {
       System.out.println("How many cans do you want?");
       quantity = sc.nextInt();
       total = quantity*sodaPricePerCan;
       System.out.println("Please pay $"+total+".");
       }
       else if(input.equals("Chips")) {
       System.out.println("How many bags do you want?");
       quantity = sc.nextInt();
       total = quantity*chipsPricePerBag;
       System.out.println("Please pay $"+total+".");
       }
       else if(input.equals("Juice")) {
       System.out.println("How many bars do you want?");
       quantity = sc.nextInt();
       total = quantity*juicePricePerBar;
       System.out.println("Please pay $"+total+".");
       }
   }
}
