                 (File $Date: 2009/11/16 18:31:26 $)

Due: November 25, 2009 (NO GRACE PERIOD!)

This is an extra-credit homework assignment. The purpose of this
homework is to be able to write a simple GUI program in Java by
using GUI frameworks such as Swing and AWT.

1. (50 points) Write a GUI application named ConnectPoint that allow
   one to create a set of points (incrementally) and connect them by
   drawing a straight line between each pair of the points (see Figure
   1 below).
     
      +-------------------+      +-------------------+
      |                   |      |                   |
      |   o               |      |   o---o           |
      |                   |      |                   |
      |                   |      |                   |
      |                   |      |                   |
      +-------------------+      +-------------------+
      |  No. of points: 1 |      |  No. of points: 2 | 
      +-------------------+      +-------------------+


      +-------------------+      +-------------------+
      |                   |      |                   |
      |   o---o           |      |   o---o           |
      |   | /             |      |   | X |           |
      |   o               |      |   o---o           |
      |                   |      |                   |
      +-------------------+      +-------------------+
      |  No. of points: 3 |      |  No. of points: 4 | 
      +-------------------+      +-------------------+

         Figure 1. Sample screens of ConnectPoint 

   The key requirements of the application include:

   R1. When a user clicks a mouse button at a position in the screen,
       a new point should be created at that position.

   R2. A straight line should be drawn from the new point to every
       existing point.
       
   R3. The number of points should be displayed all the time.

   R4. The application should provide a menu item in the menu bar and
       a tool icon in the tool bar for starting a new game.

TESTING

   Your code should compile, and run correctly under Java 1.4.2 or
   later version.

WHAT AND HOW TO TURN IN
   
   Submit your programs through the Assignment Submission page found
   in the Homework section of the course website. The page will ask
   you to zip, jar, or tar your programs, and upload a single
   file. The zip (jar or tar) file should include only a single
   directory named YourFirstNameLastName which contains all your
   source code files and other support files needed to compile and run
   your program. DO NOT INCLUDE BYTECODE (.class) FILES OR HTML
   FILES. You should turn in your programs before the class time on
   the due date.

GRADING

   You will be graded, in part, on how clear your code is.
   Excessively long code will be penalized: don't repeat code in
   multiple places. Your code should be well documented with Javadoc
   and sensibly indented so it is easy to read; regardless of their
   visibility, all classes, interfaces, fields, and methods must be
   documented with Javadoc comments.

   Be sure your name is in the comments in your code.
