Tic Tac Toe / Java

Question

我已经完成了我的第一个应用 - Tic Tac Toe。我想添加一个新功能 - 显示赢家（玩家X或O）。我该怎么做？

public class Test extends JFrame {
int counter = 0;
public Test(){
    setSize(800,800);
    setTitle("Kółko i krzyżyk");
    setVisible(true);
    setLayout(new GridLayout(3,3));
    for (int i = 1; i <= 9; i++){
    JButton button = new JButton ("");
    add (button);

button.addActionListener(new ActionListener(){
        @Override
        public void actionPerformed(ActionEvent e) {
            JButton button = (JButton) e.getSource();
            if (counter % 2 ==0){
                button.setText("X");
            System.out.println("X");
            }   else{
                button.setText("O");
                System.out.println("O");
            }
            button.setEnabled(false);
            counter++;
        }
    });
    }

}

1.Player  Class :
import java.util.Scanner;

public class Player {
    private String name;
    private MarkType mark;
    private int row, col;
    Scanner sc = new Scanner(System.in);

    public Player(String name, MarkType mark) {
        this.mark = mark;
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public MarkType getMark() {
        return mark;
    }

    public void nextMove() {

        System.out.println(this.getName() + " enter position for " + this.getMark());
        row = sc.nextInt();
        col = sc.nextInt();

    }

    public int getRow() {
        return row - 1;
    }

    public int getCol() {
        return col - 1;
    }
}

2.Board  Class :

public class Board {
    private MarkType board[][];
    private int bsize;

    public Board(int bsize) {
        this.bsize = bsize;
        board = new MarkType[bsize][bsize];
    }

        return bsize;
    }

                break;
            if (row == bsize - 1) {
                return true;
            }
        }

        if (passedRow == passedCol) {

                    return true;
                }
            }
        }

        if (passedRow + passedCol == bsize - 1) {
            for (int index = 0; index < bsize; index++) {
                if (board[index][(bsize - 1) - index] != mark)
                    break;
                if (index == bsize - 1) {
                    return true;
                }
            }
        }

    }

    public void display() {

            for (int col = 0; col < bsize; col++) {
                System.out.print(" " + board[row][col] + " ");
                if (col != bsize - 1) {
                    System.out.print("|");
                }
            }
