Tic Tac Toe java [英] Tic Tac Toe java

问题描述

我是学习Java编程的初学者，而且我正在做tic tac toe游戏。

I'm a beginner of learning Java programming and I'm doing the game of tic tac toe.

当我完成游戏后，我无法继续玩游戏，因为该程序将退出。我应该在这段代码中添加什么。由于我不使用paint方法，因此无法使用repaint（）。

When I finish my game, I can't continue to play the game, because the program will exit. What should I add to this code. Since I don't use the paint method, repaint () can't be used.

推荐答案

a ）您的整个代码适合50行。
b）你没有办法检测获胜者或完成的游戏，所以我只是在count == 9之后添加了代码。

a) Your whole code fits into 50 lines. b) You don't have a method to detect the winner or a finished game, so I just added the code after count == 9.

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

public class TicTacToeV1 extends JFrame implements ActionListener {
    private JButton [] button  = new JButton [9];
    private int count = 0;

    public TicTacToeV1 () {           
        super ("Tic-Tac-Toe");
        setSize (300, 300);
        setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
        setLayout (new GridLayout (3, 3));
        init ();
    }

    private void init () {           
        count = 0;
        for (int i = 0; i < 9; ++i) {
            button [i] = new JButton ("");
            button [i].addActionListener (this);
            add (button [i]);
        }
        setVisible (true);
    }

    public void actionPerformed (ActionEvent a) {    
        String letter = (++count % 2 == 1) ? "X" : "O";
        /*Display X's or O's on the buttons*/
        for (JButton jb : button) 
        if (a.getSource () == jb) {
            jb.setText (letter);
            jb.setEnabled (false);
        }
        if (count == 9) {
            for (JButton jb : button) 
                remove (jb) ;
            init ();
        }
    }

    public static void main (String [] args) {           
        new TicTacToeV1 ();
    }
}

我把变量部分放入它自己的方法中（init ），并从Ctor或游戏结束方法中调用它。

I put the variable part into it's own method (init), and call it from the Ctor or from the end-of-game method.

当然你也可以从那里打电话给新的Ctor。或者只是重置按钮状态和计数器。罗马有很多方法。虽然它不应该发挥作用，但在内存中使用所有按钮避免100个结束的游戏可能会节省10kb的内存。

Of course you could call a new Ctor from there too. Or just reset the button state and counter. There are many ways to Rome. While it shouldn't play a role, avoiding 100 ended games in memory with all their buttons might save 10kb of memory or so.
