Implement the following: Game(): This constructor creates a new chess game. Specifically, it should:

– Create a new Board object
– Assign the correct starting value to currentTurn.

Some of the methods from the Game class: (member variables):
• Board b: Keeps track of the state of the game (positions of pieces, captured status etc.).

• Stack< String> moveHistory: Keeps track of every move made during a game.

 Side currentTurn: Keeps track of which player’s turn it is currently.

 

CURRENT CODE:

 

public class Game {

    Board b;

    Stack<String> moveHistory = new Stack<String>();

    Side currentTurn;

 

    public Game(){

        // todo: write a constructor that initializes the game with a new board

        // hint: you are also responsible for tracking whose turn it is

    

    }

    }

 

 

ALREADY DONE CODE

public enum Side {

    BLACK, WHITE;

 

    public static Side negate(Side s) {

        return s == Side.BLACK ? Side.WHITE : Side.BLACK;

    }

}

 

 

public class Board {

    private Piece[][] pieces;

 

    public Board(){

        fillBoard();

    }

 

    /**

     * Resets the board to the starting position, and puts all the pieces in the right places.

     */

    public void fillBoard(){

        pieces = new Piece[8][8];        // Empty the board

        fillBoard(true);          // Fill black pieces

        fillBoard(false);         // Fill white pieces

    }

 

    protected void fillBoard(boolean isBlack){

        int backRank = isBlack ? 0 : 7;

        int pawnRank = isBlack ? 1 : 6;

        Side side = isBlack ? Side.BLACK : Side.WHITE;

 

        pieces[0][backRank] = new Rook(0, backRank, side, this);

        pieces[7][backRank] = new Rook(7,backRank, side, this);

 

        pieces[1][backRank] = new Knight(1, backRank, side, this);

        pieces[6][backRank] = new Knight(6, backRank, side, this);

 

        pieces[2][backRank] = new Bishop(2, backRank, side, this);

        pieces[5][backRank] = new Bishop(5, backRank, side, this);

 

        pieces[4][backRank] = new King(4,backRank,side, this);

        pieces[3][backRank] = new Queen(3,backRank,side, this);

 

        for(int i = 0; i < pieces[pawnRank].length; i++){

            pieces[i][pawnRank] = new Pawn(i, pawnRank, side, this);

        }

    }

 

    public King getKing(Side side){

        for(Piece[] array : pieces){

            for(Piece p : array){

                if(p instanceof King && p.getSide() == side){

                    return (King) p;

                }

            }

        }

 

        return null;

    }

 

    // Returns all pieces belonging to Side s.

    public List<Piece> getPieces(Side s){

        ArrayList<Piece> out = new ArrayList<Piece>();

        for(Piece[] array : pieces){

            for(Piece p : array){

                if(p != null && p.getSide() == s){

                    out.add(p);

                }

            }

        }

        return out;

    }

 

    public String toString(){

        StringBuilder sb = new StringBuilder();

        for(int i = 0; i < pieces.length; i++){

            for(int j = 0; j < pieces[i].length; j++){

                if(pieces[i][j] == null){

                    sb.append(" ");

                }else{

                    sb.append(pieces[i][j].getSymbol());

                }

            }

            sb.append("\n");

        }

        return sb.toString();

    }

 

    public Piece get(int x, int y) {

        return pieces[x][y];

    }

 

    public void set(int x, int y, Piece p){

        pieces[x][y] = p;

    }

}
