GUI Application Development, computer science homework help

Directions

You have been selected to develop a GUI application called a
“Configurator”.  The application allows
the user to complete the configuration of a computer system and produce a sales
price for the system based on the configuration selected.  The application must meet the minimum
operating requirements and specifications as provided below:

Operation

1. The user configures
   the components of a computer system by selecting items from combo boxes,
   radio buttons, and check boxes.
2. When the user clicks
   the Calculate button, the application calculates the prices of the system
   by adding the cost of each selected component to the base price of the
   system.
3. An option is provided
   to the user to clear all entries and begin over.
4. As the systems are
   configured on the “fly”, the program should update the costs automatically
   to show the user the  impact of
   adding or changing the basic system (running totals)
5. When the user presses
   the “order” button, the program should display the current configuration
   in a dialog box of your choice.  The
   dialog box should show the configuration the user is about to order with
   pricing and totals.  The user must
   confirm the configuration before the order is processed.  When the user confirms the order, the
   order is processed and the order displayed as processed.
6. When the user closes
   the frame or presses the Exit button, the application exits.

Specifications

1. You are free to use
   whatever layouts and panels you need to design the application.  You can also create any classes you
   think might be helpful to solve and develop this application. In short,
   you’re the developer and may use all resources available to you.  The only requirement is: you must use
   the Java programming language.
2. There are two base
   priced computers:
1. Intel

1. For both based
   systems, the user can select from 4 memory configurations.

1. For both based
   systems, the user can select from 3 hard drive configurations.

1. For both based

Hints

· 
Consider using separate classes to represent
each of the system configuration options.

Required Enhancements

1. 
Include sales tax at the rate of 0.078 in the
final price.  The sales tax should
display separately of total and subtotal costing.

2. 
Include combined shipping and handling rate of
0.025 based on the total cost in the total price.  The shipping and handling should display separately
of the total, subtotal and sales tax.

3. 
Use a minimum of two graphics. The graphics
could be used as buttons.

4. 
Print a summary of the configuration.  This can be done to a frame, panel or text
