AWT

Short for Abstract Windows Toolkit, the Java API that enables programmers to develop Java applications with GUI components, such as windows, buttons, and scroll bars. The Java Virtual Machine (VM) is responsible for translating the AWT calls into the appropriate calls to the host operating system. Ideally, the AWT should enable any Java application to appear the same whether it's run in a Windows, Macintosh or UNIX environment. In practice, however, most Java applications look slightly different depending on the platform on which they're executed.
