A good answer might be:

  1. Graphical Components that make up the Graphical User Interface.
  2. Listener methods that receive the events and respond to them.
  3. Application methods that do useful work for the user.

Java GUI Programming

To write a GUI application, write code for each of these three parts (while keeping the big picture in mind.) There are several ways to organize the code. If you keep the big picture in mind, the details about the various options will fall into perspective.

So far our examples have done only the first task. There were no event listeners nor application code. Our programs defined a myFrame class, constructed it, and displayed it on the monitor. Usually the first task would add many GUI components (such as buttons and text fields) to the frame. We will do this later on.


(Review: ) what is the name for methods that respond to user-generated events?
