With the skills that you have developed so far from Part I of the tutorial, you can design a graphical user interface with beauty and easy. Let us refresh ourselves before we proceed, Events are method calls that Java's windowing system performs whenever any element of a user interface is manipulated. Java events are part of the Java AWT (Abstract Windowing Toolkit) package. An event is the way that Java communicates to you, as the programmer, and to other Java AWT components that somethinghas happened. That “something” can be an input from the user (like button or mouse clicks, keypress), changes in the system environment (a window closing, opening or window being scrolled up or down), or a host of other things that might, in some way, affect the operation of the program.

To sum it up every time the user types a character or pushes a mouse button, an event occurs. Any object can be notified of the event. All it has to do is implement the appropriate interface and be registered as an event listener on the appropriate event source. Swing components can generate many kinds of events. We have covered a wide variety of these events like action event, mouse event, and keypress event and Event-Listeners like actionListener, mouseListener, and keyListener earlier. Today we will be taking a much closer look into Explicit Event-Handling and Adapters.
