Question

I need this assignment done in java with screenshots of it running.

Part I - RetailItem Class

Write a Java class named RetailItem that holds data about an item in a retail store. The class should have the following fields:

- **description**: The description field references a String object that holds a brief description of the item.
- **unitsOnHand**: The unitsOnHand field is an int variable that holds the number of units currently in inventory.
- **price**: The price field is a double that holds the item's retail price.

Write a constructor that accepts arguments for each field, appropriate mutator methods that store values in these fields, and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three RetailItem objects and stores the following data in them:

| Description | Units on Hand | Price |
|------------------|---------------|-------|
| Item #1: Jacket | 12 | 59.95 |
| Item #2: Designer Jeans | 40 | 34.95 |
| Item #3: Shirt | 20 | 24.95 |

Create an array in which you save the items described above.

Part II - CashRegister Class

Write a CashRegister class that can be used with the RetailItem class that you wrote. The CashRegister class should simulate the sale of a retail item. It should have a constructor that accepts a RetailItem object as an argument. The constructor should also accept an integer that represents the quantity of items being purchased. In addition, the class should have the following methods:

- The **getSubtotal** method should return the subtotal of the sale, which is the quantity multiplied by the price. This method must get the price from the RetailItem object that was passed as an argument to the constructor.

- The **getTax** method should return the amount of sales tax on the purchase. The sales tax rate is 6 percent of a retail sale.

- The **getTotal** method should return the total of the sale, which is the subtotal plus the sales tax.

Demonstrate the class in a program that performs the following tasks:
- Displays the list of items available in the store.
- Prompts the user to enter an item number and reads the value.
- Asks the user for the quantity of items being purchased.
- Displays the sale’s subtotal, amount of sales tax, and total.

Save the purchases in an array of type CashRegister.
