Use Java program to add a method printReceipt to the CashRegister class. Then create a driver class that asks the user to input the 5 items that they have bought recently and also the prices for each item, and print the items, their prices, and the total amount due. Hint: You will need to form a string of all prices. Use the concat method of the String class to add additional items to that string. To turn a price into a string, use the call String.valueOf(price). Also, the payment information will need to be the same as the price information. Here is the CashRegister class: /** A cash register totals up sales and computes change due. */ public class CashRegister { private double purchase; private double payment; /** Constructs a cash register with no money in it. */ public CashRegister() { purchase = 0; payment = 0; } /** Records the sale of an item. @param amount the price of the item */ public void recordPurchase(double amount) { purchase = purchase + amount; } /** Processes a payment received from the customer. @param amount the amount of the payment */ public void receivePayment(double amount) { payment = payment + amount; } /** Computes the change due and resets the machine for the next customer. @return the change due to the customer */ public double giveChange() { double change = payment - purchase; purchase = 0; payment = 0; return change; } }
