Part 4: Build the Game board At this point, we are ready to create the ChessBoard itself. This time, I will not provide you the test code. You must write both the ChessBoard class and the (client) test application. Note: The most difficult part ahead (other than objects) is the use of 2D arrays. ChessBoard Now we have 6 classes, and look at the relationships between classes! -activeColour:ChessColour -fullMove:int -board:Squarelll Square +ChessBoard() +ChessBoard(positions:Coordinatell, pieces:Pieces[) Coordinate +getSquare(c:Coordinate): Square Piece +reset() +move(src:Coordinate, dest:Coordinate):boolean
