Implement your interface from Chapter 7 using event handling In Chapter 7 your assignment was to Design a universal remote control for an entertainment system (cable / TV, etc). Create the interface as a NetBeans project. Or implement the design of the telephone interface for a smartphone.

The assignment cannot be created using the GUI Drag and Drop features in NetBeans. You must actually code the GUI application using a coding framework similar to one described and illustrated in chapter on GUI development in the courses textbook.

In this assignment you need to have event listeners associated with the components on the GUI. This assignment is about creating a few event handlers to acknowledge activity on you interface. Acknowledgment of activity can be as simple as displaying a text message when an event occurs with a component on your interface such as; a button is pressed, a check box or radio button is clicked, a slider is moved or a combo box item is selected.
