Preface The Abstract Window Tookit (AWT) provides the user interface for Java programs. Unless you want to construct your own GUI or use a crude text-only interface, the AWT provides the tools you will use to communicate with the user. Although we are beginning to see some other APIs for...
Core Java by Cay S. Horstmann and Gary Cornell was originally published in the Java series of Sun Microsystems Press and is now published by Prentice-Hall. The book is aimed at experienced programmers who want to learn how to write useful Java applications and applets. No hype, no toy code...

After completing this chapter, you will be able to draw strings, images, and shapes via the Graphics class in your Java programs. We discuss geometry-related classes—Polygon, Rectangle, Point, and Dimension, and the Shape interface—you will see these throughout the remaining AWT objects. You...

But the APIs that implement it are not well understood by some developers -- a problem that has led to programs not performing as well as they could. - By Amy Fowler Java 2D Web site.This article explains the AWT and Swing paint mechanisms in detail. Its purpose is to help developers...

The Abstract Windowing Toolkit (AWT) is the first set of nontrivial, publicly available, basic objects with which to build Java programs, with the focus on graphical user interfaces, or GUls. The AWT was built by Sun's JavaSoft unit and is provided free
This class and its subclasses supercede the original java.awt.Event class. Subclasses of this root AWTEvent class defined outside of the java.awt.event package should define event ID values greater than the value defined by RESERVED_ID_MAX. The event masks defined in this class are needed ...
