The establishment called ABC Enterprise requires a Java program to keep a

database of the inventory of the products that it sells. Each product is identified by

its manufacturer

, its name, the quantity, and unit price. In addition to storing the

information, the program should be able to make updates to the quantity and/or

the price as time goes on. That is, when a sale is made, the quantity of that product

must be reduced; similarly, when a product is re-ordered, the quantity of that

product must be increased. Also, when there is a change in the price of a product,

the price must be changed. The change must be interpreted as a replacement of

the value. New products may be added to the inventory at any time; also, a product

may be removed from the inventory at any time. Maintain a separate list of those

products that have been deleted from the database of active products.

Your program must be able to produce three kinds of reports, namely:

1. Locate a single product and display its name, price and quantity alone.

2. The inventory report should be structured as follows:

Product

Purchase Date

Quantity

Price

Manufacturer

In your design, convince yourself that you need a minimum of four classes, not

including the test class Product, Manufacturer, Address, and Database.

Also, you will be provided with the class called IO.java (that we discussed in class)

for input and for output purposes only. Use a scrollable pane to display your

outputs for requirements 2 and 3. Use JOptionPane alone for requirement 1.
