我已经实现了游戏 tictactoe 的最简单的解决方案，我使用了一个 gui 来表示它。所以我问你是否可以给我一些建议和想法，如何让它更优雅。我要改进的部分是井字游戏类以及mousePressed 和mouseEntered 方法。这是代码。

/**The TicTacToe class with the GUI

public class TicTacToe extends JFrame implements MouseListener
{
    JLabel[] jl ={

            new JLabel()} ;

    ImageIcon[] ox = {
            new ImageIcon("tic/o.gif"),
            new ImageIcon("tic/x.gif")  
    };

    static boolean isFirst;
    static int counter = 1;

    public TicTacToe()
    {

        JPanel panel = new JPanel(new GridLayout(3,3));

        Border border = new LineBorder(Color.red, 2);
        Border border2 = new LineBorder(Color.blue, 2);



        for(int i=0; i<jl.length; i++)
        {
            jl[i].setBorder(border2);
            jl[i].addMouseListener(this); 
            panel.add(jl[i] );
        }
        panel.setBorder(border);
        this.add(panel);




    }

不要将图标用作状态！为板子和字段上的标记使用适当的（数字）模型，例如

int[] board = new int[3][3];
final static int X_MARK = 1;
final static int O_MARK = -1;

因此，如果玩家点击某个区域，

  1. 检查该字段是否为空（对应的数组单元格的值为 0）
  2. 将单元格值更改为 1 或 -1
  3. 计算我们是赢家还是平局（只需计算行、列和对角线的总和，如果总和为 3 或 -3，则我们有赢家，否则，如果没有字段为 0，我们有平局）

然后，使用模型更新板视图。
