    }

    pack();
    setVisible(true);
}


public void actionPerformed(ActionEvent e){
    count ++;
    int i = 0;
    for(i = 0; i < 9; i++){
        if(button[i] == e.getSource()){
            if(sign % 2 == 0){
                button[i].setText("X");
                button[i].setEnabled(false);
            }
            else {
                button[i].setText("O");
                button[i].setEnabled(false);
            }
            break;
        }
    }

    if(isAWinner(i) && count > 2){

        JOptionPane.showMessageDialog(null, "" + button[i].getText() + "s Win");
        for(int j = 0; j < 9; j++){
            button[j].setText("");
            button[j].setEnabled(true);
        }
        count = 0;
        sign = 0;
        return;
    }



    if(count >= 9){
        JOptionPane.showMessageDialog(null, "Cat's Game!");  
        for(int j = 0; j < 9; j++){  
            button[j].setText("");  
            button[j].setEnabled(true);  
        }  
        count = 0;  
        sign = 0;  
        return;  
    }  

    sign++;  

}

所以这很好用，tic tac toe本身的游戏没有任何问题我的问题是当我尝试制作这些游戏的网格时

import java.awt.Container;
import java.awt.GridLayout;

import javax.swing.JFrame;

public class TicTacTest{

public static void main(String[] args) {

    JFrame frame = new JFrame();
    frame.setTitle("Super TicTacToe");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(900,900);
    Container pane = frame.getContentPane();
    pane.setLayout(new GridLayout(3,3));

        Game[] games = new Game[9];

        for(int i = 0; i < 9; i++){

            games[i] = new Game();
            pane.add(games[i]);
        }


        frame.setVisible(true);

    }

}

我认为这样可行，但显然我错了，因为什么都没有出现。

我应该在主要内容中制作9个Tic Tac Toe板？

Game从JFrame延伸，无法将其添加到其他类型的容器中（这只是愚蠢的）

这个例外会说得那么多......

Exception in thread "main" java.lang.IllegalArgumentException: adding a window to a container   
    at java.awt.Container.checkNotAWindow(Container.java:488)   
    at java.awt.Container.addImpl(Container.java:1089)  
    at java.awt.Container.add(Container.java:415)

相反，让Game从JPanel延伸，然后将其添加到您想要的任何容器中

像...一样的东西。
