/* applets do not run by themselves.  they run as part of a web browser
or the appletviewer.  To run an applet, an .html file is needed that
contains the HTML applet tag whose code attribute is the name of the 
.class file:

<applet code="FirstApplet.class" width="600" height="600">
</applet>

The html file can be any name but for organizational purposes we'll use
the same name as the applet.
Compile the Java source file and then execute the .html in JCreator to 
test it.  The appletviewer will run.
The applet can also be run in a web browser by opening the .html file.

Summary:
FirstApplet.java ---- compiled ---> FirstApplet.class
FirstApplet.html has the above two lines.
Have all three files in the same folder.


[Norton irritation: antivirus software can be configured to disallow running
of applets, so check/change your home computer's Norton settings to
allow running applets.]
