This chapter examines Java applets. The methods of an applet are called by another program, usually a Web browser. The applet is responsible for the graphical components and user interaction in a rectangular section of the Web browser's screen. Applets run on the same computer as the Web browser and are typically used so that the user can interact with the Web page.
Applet class.Graphics Objects.drawString() Method.setBackground() and setColor() methods.paint() method.drawOval() method.drawRect() method.drawLine() method.
These notes discuss the
Applet class that is part of
the AWT
(Application Windowing Toolkit).
A newer class, JApplet,
is part of the Swing set of components.
However, as of this writing,
JApplet is not commonly used,
and so will not be discussed.
(See chapters 55 through 64 for a discussion of Swing).
