From Java Tutorial - Spring 1997 Part 3:Graphics and the Abstract Windowing Toolkit Peking Tutorial, Web Certificate -- Spring-Summer 1997. by Nancy J. McCracken,Geoffrey C. Fox
Canvas is a simple class which are used to draw on as in artist's canvas. They cannot contain other components. This is the class on which you use the graphics methods.
Upto now, we have described how to build typical Applet panels inside browser window. There are classes that allow one to generate complete windows separately from the browser window
Window Class has subclasses Frame and Dialog
Frame("TitleofWindow"); // creates a window with memubar and given title
  • Note Frame is a Container and can thereof be defined hierarchically with components that are laid out by LayoutManagers
  • Note a Frame in Java is NOT THE SAME as a frame in Netscape 2.0 and higher
