The Abstract Windowing Toolkit provides Java's fundamental graphics capability. You can program the AWT directly, or you can use other packages such as Swing if you want to write your applications at a higher level. The AWT is most often used for interactive applications, either for providing local GUIs or applets, but it can also be used as a painting tool for the production of .jpg or .png outputs.
