CHESS GAME INTERFACE AND ITS SOURCE CODE

THE CHESS BOARD
Introduction
The aim of the assignment was to write a program that would produce a chess board with all its pieces in place. The program was aimed at using the concepts of 2-dimension graphics in Java namely Graphics and Graphics2D. Initially, it was planned that the program will use all the images of a normal chess board. But due to internet service problems, I failed download other images like Queen, King, e.t.c, instead I used few available pieces to fill the board.

Snapshot

The above diagram is the output of running the attached source code below. I have deliberately used the black and blue color (instead of black and white) so that it is different from those that people have already programmed. Unfortunately, if you run it on your computer, the images of the chess board pieces will not be displayed (since they are kept in my computer).



Conclusion
By coming up with the program, I have realized that not only can I write a program that displays field and labels, but also can display real life objects such as chess. I will try as much as possible to see that I extend the program so that people should be able to play it.
