我是Java编程的新手，并且正在开发一个使用Swing的简单单人TICTACTOE游戏。你是两节课。一个主要的TICTACTOE类，它使用XOButtton类来设置可以侦听单击事件的按钮。我首先创建该tictactoe类的对象，然后使用该对象调用一个名为initialCheckButton的方法，以查明是否已单击按钮3次。如果是，则调用另一种方法来确定X或O是否连续显示。如果是，则获胜。我计划对此进行进一步开发，但这只是一个模板。当GUI dsiplay播放时，单击按钮并显示连续的X或O不会显示JoptionPane的消息。有什么帮助吗？
public class TicTacToe extends JFrame {
JPanel p = new JPanel();
boolean done = false;
XOButton buttons[] = new XOButton[9];
public static void main(String args[]) {
TicTacToe t = new TicTacToe();
t.initialCheckButton();

setDefaultCloseOperation(EXIT_ON_CLOSE);
p.setLayout(new GridLayout(3, 3));
for (int i = 0; i < 9; i++) {
buttons[i] = new XOButton();
p.add(buttons[i]);
}
add(p);
setVisible(true);

public void initialCheckButton() {
