Graphics Concepts in Java Applets
One kind of Java program is an applet, which is a program that can run in (most) web browsers such as Netscape.
The name of the applet is given in an <APPLET> tag in an HTML file.
Think of a Java applet as a graphics window on which to draw text and other objects.
The graphics window has a particular width and height as specified in the <APPLET> tag
The origin is in the top left-hand corner of the graphics window: the x-coordinate increases from left to right, while the y-coordinate increases from top to bottom
