Subject: Instance variables, instance variables, instance variables...

Hi 061 Java students,

     You will need to have THREE PRIVATE INSTANCE VARIABLES in your
Java program that is due Friday, if you want to make the noCircle
and the noSlash disappear and reappear, and if you want to make
the Clicking Text message change from Plain to Bold and back again
with the setPlain() and the setBold() methods.

     Here is the format of a Java class definition:

     class header
     {
         // 1.  instance variables portion.


         // 2.  methods portion including begin() method, possibly,
         //     and including mouse event methods.

     }

We will talk about this on Wednesday (tommorrow) in class.

Be sure to check out the web page and see a new version of the
original Scribble program.  It scribbles in colors and allows you
to create cool graphics effects too.

http://www.cns.uni.edu/~jacobson/061 and follow links to the new
web page example.

See you in class!

Mark
