For computer games, the keyboard and mouse are the primary methods of interacting with the computer. The problem is, while Java has great support for these input devices for GUI applications, computer games need to handle the input a little differently. Although there are no built-in classes that give us what we need, we can easily create our own, learn a little something in the process, and have a lot of fun doing it. So grab your favorite drink and get coding.

Active rendering is a style of programming that allows Java code to handle all of the rendering in a simple while loop. This approach resembles traditional game programming, allowing more time to be spent developing a game and less time spent worrying about which paint method to override. There are two different kinds of rendering: active and passive. Anyone who has ever written a swing application has experienced passive rendering.
