Homework #3 -- sample code

The instructor's version of homework #3 consists of one source file, SwingTest03.java. The program makes use of an inner class, ShapeEntry, which encapsulates the generation and painting of a random Shape2D subclass.

The program conforms to the assignment with the following minor differences:

• Its package name is com.bozoid.cis370.hw03 rather than cis370.hw03.
• It prints (to standard output) the string "paintComponent()..." every time paintComponent() is called.
• It prints a list of its randomly-generated ShapeEntry objects when they are generated.

Here is a sample compile, javadoc, and run of the program.

D:\CIS370\code>javac -d classes -sourcepath sources     sources\com\bozoid\cis37
0\hw03\*.java
