Java swing五子棋的实现方法

今天给大家介绍一下如何用Java swing实现五子棋的开发即用Java开发图形界面程序五子棋，代码由于太多，只贴部分，最下面会附上下载地址，废话不多说，下面我们先看一下运行结果：

接下来我们看代码：

首先是创建主frame框架界面：

package org.liky.game.frame;

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Toolkit;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class FiveChessFrame extends JFrame implements MouseListener, Runnable {

 // 取得屏幕的宽度
 int width = Toolkit.getDefaultToolkit().getScreenSize().width;
 // 取得屏幕的高度
 int height = Toolkit.getDefaultToolkit().getScreenSize().height;
 // 背景图片
 BufferedImage bgImage = null;
 // 保存棋子的坐标
 int x = 0;
 int y = 0;
 // 保存之前下过的全部棋子的坐标
 // 其中数据内容 0： 表示这个点并没有棋子， 1： 表示这个点是黑子， 2：表示这个点是白子
 int[][] allChess = new int[19][19];
 // 标识当前应该黑棋还是白棋下下一步
 boolean isBlack = true;
 // 标识当前游戏是否可以继续
 boolean canPlay = true;
 // 保存显示的提示信息
 String message = "黑方先行";
 // 保存最多拥有多少时间(秒)
 int maxTime = 0;
 // 做倒计时的线程类
 Thread t = new Thread(this);
 // 保存黑方与白方的剩余时间
 int blackTime = 0;
 int whiteTime = 0;
 // 保存双方剩余时间的显示信息
 String blackMessage = "无限制";
 String whiteMessage = "无限制";

 public FiveChessFrame() {
 // 设置标题
 this.setTitle("五子棋");
 // 设置窗体大小
 this.setSize(500, 500);
 // 设置窗体出现位置
 this.setLocation((width - 500) / 2, (height - 500) / 2);
 // 将窗体设置为大小不可改变
 this.setResizable(false);
 // 将窗体的关闭方式设置为默认关闭后程序结束
 this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 // 为窗体加入监听器
 this.addMouseListener(this);
 // 将窗体显示出来
 this.setVisible(true);

 t.start();
 t.suspend();

 // 刷新屏幕,防止开始游戏时出现无法显示的情况.
 this.repaint();

 /*

 this.addMouseListener(this);

 this.setVisible(true);
 }

 public void paint(Graphics g) {

 /*g.drawOval(20, 40, 40, 40);*/
 /*g.fillOval(20, 40, 40, 40);*/
 /*g.drawLine(20, 40, 80, 40);*/

 try {

 }
