Basic AWT classesObjects of these classes have a familiar appearance on the screen. They are have the property that it is unusual to display another object inside them (in fact, in Java it is impossible to put an object inside one of these basic objects).

The pictures shown below were taken from a Java program running on a Windows NT system. The appearance on other system will be slightly different, as illustrated below. Button
