IN JAVA COMPLETE THE PROGRAM

You are going to write a program that checks chess moves for legality and display possible moves a chess piece might make. You will start by writing an abstract parent for all of our different chess pieces called

ChessPiece. Then you will write Knight, WhitePawn, Rook, Bishop, and Queen classes. I have

provided a King class as an example and a BlackPiece class $($which is used as a dummy class for

all black pieces$).$ We will only test with white pieces. I have also provided a Board class and a

ChessMoveChecker program class for you.

The abstract ChessPiece Class

This class must have exactly the following protected instance variables $($attributes$/$fields$)$:

$$ rowNum: an integer specifying the row of the board the piece is on

$$ columnNum: an integer specifying the column of the board the piece is on

$$ pieceColor: an integer specifying the color of the piece $($using a constant from Board$)$

This class must have at least the following public methods. You may wish to add additional

protected methods that have logic needed by multiple subclasses:

$$ A constructor that takes in values for all three instance variables.

$$ A move method that takes the new row and column as parameters and updates the

piece$$s location instance variables.

$$ A getColor method that returns pieceColor.

$$ An abstract getLabel method that returns a character and takes no parameters.

$$ An abstract isLegalMove method that returns a boolean and takes three parameters: an

integer destRow representing the destination row, an integer destCol representing the

destination column, and a Board object theBoard, which is the chess board we$$re using.

$$ An abstract generateLegalMoves void method that takes two parameters: a $2$D array of

characters boardData that we will use for showing where the piece can move and a

Board object theBoard.

You will then create the following subclasses of ChessPiece. I highly recommend doing them in

this order.

$$ Knight

$$ Rook

$$ WhitePawn $($because pawns move in only one direction, the different colors behave

differently, unlike other pieces$)$

$$ Bishop

$$ Queen
