The AWT peer interfaces are implemented by platform-specific peer classes that access the platform’s own toolkit using native methods (that is, methods implemented in a language other than Java). For example, an AWT button has three Javalanguage layers: • Button, a class in the java.awt package • ButtonPeer, an interface in the java.awt.peer package • a platform-specific button peer class containing native metho
