CIS355A Week 3 Lab

Enhanced GUI Application using Additional Swing Components



  • 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



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.
