(a) Understand the concepts cohesion, and how it can be used to decompose problem definition into separate components(classes).

(b) Understand t and coupling and how it is used to assemble the components (classes)into complete programs.

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.

Note: a manufacturer is characterized by its company's name and address 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 the products that have been deleted from the database of active products.

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

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

(b) The inventory report should be structured as follows:

Product PurchaseDate Quantity Price Manufacturer State

Telephone 01/20/2013 10 254.99 Motorola FL

Computer 01/06/2013 15 756.99 CBS NY

: : : : : :

Product Date Manufacturer

Paper reams 01/20/2013 Morgan Jewelry

: : :

In your design, convince yourself that you need a minimum of four classes, not including the test class - Product, Manufacturer, Address, and Database.

You may use the class called GetData.java, Listing 1.6 (in the textbook) , for inputting the data. Use a scrollable panes to display your output.
