I am trying to create a menu GUI. I think I am having problems with the action listeners Any help would be great. Thanks
Write an GUI application that display a menu system. The menu system should allow the user to select one package, one phone, and any of the options desired. As the user selects items from the menu, the application should show the prices of the items selected.
(This GUI application uses AWT and SWING imports to display the menu system)
Question Details:
Cell Solutions, a cell phone provider, sells the following packages:
300 minutes per month: $45.00 per month
800 minutes per month: $65.00 per month
1500 minutes per month: $99.00 per month
The provider sells the following phones. ( A 6% sales tax applies to the sale of a phone.)
Model 100: $29.95
Model 110: $49.95
Model 200: $99.95
Customers may also select the following options:
