Lab #10: 

Project 3 Progress

Here are some suggested steps that we can help you with in lab.  Feel
free, though, to substitute other parts of the project.

1. Generate some test cases for your project solution.  You may use the
   'checkers' program now available on the CS61B accounts: the command is
	checkers OPTIONS
   (no "java" in front) where the OPTIONS are as specified for the assignment.

2. If you haven't already done so, copy the new subdirectory
   ~cs61b/hw/proj3/eg into your project 3 directory.  Compile the
   PingPong class, set up two instances of it (possibly on two
   different terminals), and get them to communicate.  (All terminals
   in the same lab actually connect to the same machine, so you can
   use 'localhost' as the host.  You might try logging in to another
   machine---such as nova, pulsar, or quasar---and see whether you can 
   set up communication between two different machines.

3. Create a new program, Chat.java, by copying PingPong.java and modifying
   it so that instead of the program constructing artificial messages, it
   reads lines from the terminal and sends those to the other program.
   Make a program hang up when you type "quit" to it (alone on a line).

You can adopt the code in the eg subdirectory to the implementation of
RemotePlayer (or whatever you decide to put in its place, if you don't like 
our program structure).

4. Implement the Move class.  You needn't bother implementing all the create
   methods.  If you'd prefer, just implement the ones you end up using.
   However, do add one method:
	static Move parseMove (String move) { ... }
   that converts the String form of move (as typed by the user or sent 
   in a message) into the appropriate Move object.

5. Implement enough of Checkerboard that makeMove works (the comment
   indicates that makeMove can assume that the move is legal).

6. The skeleton suggests having legalMoves return an iterator.  Another
   possibility (which you might find easier) is to have it return the list
   of Moves, instead.  To start with, try getting it to give you a list
   or iterator of legal Moves for the side that is to move, ignoring 
   jumps (the real rules of checkers require that legalMoves give you 
   ONLY jumps if some jump is possible).  (I have added a couple of
   arrays to ~cs61b/hw/proj3/game/Move.java that give the numbers of all
   squares that are within one move or within one jump of a given 
   square.  Feel free to use them, if you find them convenient.)
