RetailItem Class

Write a class named RetailItem that holds data about an item in a retail store. The

class should have the following fields:

• name. The name field references a String object that holds the name of the

item.

• quantity. The quantity field is an int variable that holds the number of items

represented by the instance.

• price. The price field is a double that holds a single item’s retail price.

Write a constructor that accepts arguments for each field, accessor methods that

return the values in these fields, a totalCost() that returns the cost of all quantity

items, and a toString() method that returns a formatted string for the Sales

Receipte below.

CashRegister Class. Write a CashRegister class that can be used with the RetailItem

class above. The CashRegister class should simulate the sale of a series of

RetailItems. It should have one field, items, an ArrayList of Retail

Items and the following methods:

• addItem method accepts a RetailItem object.

• printItems method takes no arguments, but prints all the items.

• getSubtotal method should return the subtotal of the sale, which is the sum of

the retail items added so far. This method must get the price from each

RetailItem object that was passed as an argument to the addItem method.

• getTax method should return the amount of sales tax on the purchase. The sales

tax rate is 6 percent of a retail sale.

• getTotal method should return the total of the sale, which is the subtotal plus

the sales tax.

Demonstrate the class in a program that asks the user for the name, quantity and

price of items being purchased repeatedly until an empty line is entered, and then

displays a sales receipt .
