                             13 June 2000


Due: Tuesday, June 13 at midnight

Late penalties: 20 points per partial day late.  That is, programs
	turned in after midnight Tuesday and before midnight Wednesday
	will have 20 points deducted for late, programs turned in after
	midnight Wednesday and before midnight Thursday will have a total
	of 40 points deducted for late, etc.

Total point value of assignment:  100 points

Late submissions not accepted after: Friday, June 16 at midnight

This assignment is to be done INDIVIDUALLY.



Create a directory, A5, which will contain all parts of this assignment.
The directory will contain a class named Ngon.java.  Ngon.java should
have a "public static void main (String [] args)" method which you
use to test your code.

The objectives of this program are to give you some experience writing
an entire class and implementing an interface.

You are to construct an Ngon class, which implements the Drawable
interface found on pages 311-312 of Java Elements.  You will have
compiler errors unless all methods in the interface are present,
but these may be represented by stubs during development.

You should have the following constructors:

	public Ngon(int n)
	// post: constructs a regular polygon with n sides
	//       Let 100 be the (arbitrary) radius of the polygon

	public Ngon (Ngon other)
	// post: generates a copy of other  (i.e., copy constructor)

	public Ngon (int n, int radius)
 	// post: constructs a polygon with n sides and radius radius

	public Ngon (Pt [] args)
	// post: constructs a polygon from the array of points

   
Input:

 	None required, but your main method may input values if
	you wish.

Output:

	Print your name, the assignment number, and a short description
	of the assignment to the screen.

	Your main method should write appropriate messages to the
	screen to indicate methods being tested.

Other requirements:

	Follow the style standards to be found on your instructor's
	web page for CPSC 210.

	Submit your program using the handin command.  There is a link to
	the handin description on your lab page (www.cs.clemson.edu/~lab210).


Grading rubric:

	Required documentation and style standards:  10 pts.

	The program compiles without error (and must include the
	   statement "implements Drawable" in class declaration.  10 pts.

	Program must compile for further points to be awarded.
	   (Max points for programs that don't compile: 10)

	Constructors:  5 pts. each = 20 pts.
	Methods:  height, width, left, right, bottom, top, two
	    center methods (5 pts each = 40 pts.)
	Methods:  drawOn, clearOn (5 pts. each = 10 pts.)
	Method:  fillOn (10 pts.)

	Quality of test program:  10 pts.

	Note:  The sum of the above points is 110.
