Question

The cash register program will have items. For each item, the name and cost are saved. For a transaction, it will accept any number of items (not known in advance) and any number of payments of different payment types (not known in advance). For each transaction, it calculates the total including a 7% sales tax and keeps prompting for a payment until the total has been paid. It also determines if any change is required. Thus, a transaction is responsible for calculating the amount of money that needs to be paid, accepting money, and generating a receipt. A receipt holds information about a transaction so that it can display how much each item cost, how the transaction was paid for, etc. (see example outputbelow).Payment type includes CASH, DEBIT_CARD, CREDIT_CARDandCHECK. Each payment consists of an amount and payment type
Hints
1. All fields should be private.
2. The PaymentType class should be an enum class with values: CASH, DEBIT_CARD, CREDIT_CARD, CHECK
3. Payment type information should not print the enum directly
4. Use final to store the transaction for each receipt.
5. Output:
A. The values for subtotal, tax, total, and payment information are all aligned. You can achieve this by using the tab character '\t' in your Strings. The item lines do not need to be aligned.
B. Do not worry about only using 2 decimal places. Let Java decide how many decimal places to use.
6. Create a main class to house the main method. In the main method, create some items, a transaction, and display the receipt.
A. Example outputs
Example: Pay everything with one payment

Item 1: apple: 0.5

Explanation:

package sample;

import java.util.Scanner;

public class Main extends newOrder{

   public static void main(String[] args) {

       newOrder order = new newOrder();

       order.newOrder("apple", 0.5);

       order.newOrder("pear", 0.75);

       order.newOrder("pineapple", 0.75);

       double newTotal = order.getTotal();

       order.printItems();

       order.printTotal();

       while (newTotal != 0) {

           Scanner in = new Scanner(System.in);

           System.out.println("Please enter payment type.\n" + "Cash \nDebit card \nCredit card \nCheck");

           String paymentType = in.nextLine();

           System.out.println("Enter the amount to pay with this type: ");

           double amount = in.nextDouble();

           newTotal -= amount;

           System.out.println("Total after payment: " + newTotal);

       }

       System.out.println("Receipt Printed:");

       order.printItems();

       order.printSubtotal();

       System.out.println("Tax: 7%");

       order.printTotal();

   }
