Question

我正在使用Java创建一个TicTacToe游戏，我想要一些帮助。

在玩家获胜后我希望游戏要求复赛。发生了这种情况，但按钮面板并不令人耳目一新。我使用了“重绘”功能，但它似乎不起作用。提前谢谢

以下是代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.util.*;

public class TicTacToeGUI extends JFrame implements ActionListener{

    JButton btn1;

    JButton btn7;
    JButton btn8;
    JButton btn9;
    public JFrame window = new JFrame("Tic Tac Toe");
    public int playerTurn = 0;
    public boolean win = false;
    String letter = "";
    private final String[] yesno = {" ", "Yes", "No"};

    public TicTacToeGUI(){

您需要将文本设置为空

setText("");

//伪代码

foreach(Button temp in windows.allChild) {
    temp.setText("");
}
windows.repaint();
