This applet practices the squares of the chessboard. It asks for a random square on the chessboard. The user should make a (mouse)click on the specific square; can ask for another similar task, and can give up. When giving up; the square that is looked for is colored red; the last square clicked is also colored red.
This applet was made in October 1997. Information used came mainly from Jeroen Fokker's Imperatief Programmeren, (class-notes for 1st years programming course, where I am assisting); and the book Java, How to Program by Deitel and Deitel.
