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：

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();
