CIS355A Week 3 Lab

Enhanced GUI Application using Additional Swing Components

 

OBJECTIVES

• Create a GUI that uses JCheckBox, JRadioButton, JTextArea, and menus.
• Process multiple events.

 

 

PROBLEM: BurgersRUs Point of Sale system

Burger Barn needs a point of sale application. The products and prices are as follows.

Burgers:                                          single $3.50, double $4.75

Add cheese:                                  + $.50

Add bacon:                                   + $1.25

Make it a meal:                           + $4.00

 

FUNCTIONAL REQUIREMENTS

You can code the GUI by hand or use NetBeans GUI builder interface.

The GUI should use JRadioButton to choose single or double burger.

• Single burger
• Double burger

It should use JCheckBox for add ons.

• Add cheese
• Add bacon
• Make it a meal

JTextField for item price, order quantity, order total

JTextArea to display the receipt

Create a menu with the following options.

File                                                   Order

   Exit                                                 Add to Order

                                                            Clear for next item

                                                            New Order

 

As the user selects items, the item price should be calculated and updated accordingly.

Note that quantity should default to 1. The user can change if needed.

Once choices are made and quantity is entered, process the order using the menu options.

Order—Add to Order                  Displays the choice and price in each text area.

                                                           Note that multiple items can accumulate in a single order

                                                           Updates the order total

Order—Clear for next item       Clears the checkboxes. Note that quantity should default to 1

Order—New Order                      Clears the GUI and totals for a new order

File—Exit                                         Exits the program.  Use System.exit(0) commad.

Objective/Purpose of the program

Briefly describe the program’s requirements.

 

 

Analysis/Design 

Describe the approach/structure of program. What classes/functions were used?

 

 

Testing/Results

Does your program satisfy all requirements of the lab?

If yes, how did you test it? Indicate test cases used, expected values, and show results with screen shots.  For example:

 

Case	Description	Test Data	Expected Result	Actual Result
1	Describe what you are testing	Specify the test data	What is expected	Actual results – reference an image that you include below.

 

If any requirements are NOT met, document the known issues.  What did you do to try to solve them?

Make sure you demonstrate in your testing the parts that are working correctly.

 

Conclusions / Lessons Learned

What difficult problems did you encounter, and how did you handle them?

What new concepts did you learn/reinforce with this lab?

Is there anything you would have done differently?
