JAVA

Purpose of Assignment To help you to: (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 Purchase Date Quantity Telephone 01/20/2013 10 Computer 01/06/2013 15 Price Manufacturer State 254.99 Motorola 756.99 CBS FL NY (c) A list of the deleted products should be structured as follows: Product Date Manufacturer aper 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.
