/**
 * CircleWindow shows how to create a simple subclass
 * of JFrame.  When you instantiate a CircleWindow object
 * (as is done in main, for example), it initializes its
 * own size and position and then makes itself visible.
 * When the window's contents need to be drawn, the Java
 * Virtual Machine calls the CircleWindow object's paint
 * method.
