Java五子棋的实现（附源码）

学习目的：熟悉java中swing类与java基础知识的巩固.(文末有源代码文件和打包的jar文件)
效果图：
思路：**1.首先构建一个Frame框架，来设置菜单选项与按钮点击事件。
MyFrame.java文件代码如下

package StartGame;import javax.swing.ButtonGroup;import javax.swing.Icon;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JMenu;import javax.swing.JMenuBar;import javax.swing.JMenuItem;import javax.swing.JOptionPane;import javax.swing.JRadioButtonMenuItem;import java.awt.Color;import java.awt.Component;import java.awt.Container;import java.awt.Graphics;import java.awt.Toolkit;import java.awt.event.ActionListener;import java.awt.event.MouseEvent;import java.awt.event.MouseListener;//窗体框架类public class MyFrame extends JFrame {    // static boolean canPlay1 = false;判断是否可以开始游戏    final MyPanel panel = new MyPanel();    public MyFrame() {        // 设置窗体的大小并居中        this.setSize(500, 600); // 设置窗体大小        this.setTitle("五子棋游戏"); // 设置窗体标题        int width = Toolkit.getDefaultToolkit().getScreenSize().width;// 获取屏幕的宽度        int height = Toolkit.getDefaultToolkit().getScreenSize().height;// 获取屏幕的高度        this.setLocation((width - 500) / 2, (height - 500) / 2); // 设置窗体的位置（居中）        this.setResizable(false); // 设置窗体不可以放大        // this.setLocationRelativeTo(null);//这句话也可以设置窗体居中        /*         * 菜单栏的目录设置         */        // 设置菜单栏        JMenuBar bar = new JMenuBar();        this.setJMenuBar(bar);        // 添加菜单栏目录        JMenu menu1 = new JMenu("游戏菜单"); // 实例化菜单栏目录        JMenu menu2 = new JMenu("设置");        JMenu menu3 = new JMenu("帮助");        bar.add(menu1); // 将目录添加到菜单栏        bar.add(menu2);        bar.add(menu3);        JMenu menu4 = new JMenu("博弈模式"); // 将“模式”菜单添加到“设置”里面        menu2.add(menu4);        // JMenuItem item1=new JMenuItem("人人博弈");        // JMenuItem item2=new JMenuItem("人机博弈");        // 设置“”目录下面的子目录        JRadioButtonMenuItem item1 = new JRadioButtonMenuItem("人人博弈");        JRadioButtonMenuItem item2 = new JRadioButtonMenuItem("人机博弈");        // item1按钮添加时间并且为匿名类        item1.addMouseListener(new MouseListener() {            @Override            public void mouseReleased(MouseEvent e) {                // TODO Auto-generated method stub            }            @Override            public void mousePressed(MouseEvent e) {                // TODO Auto-generated method stub                Icon icon = new Icon() {                    @Override                    public void paintIcon(Component c, Graphics g, int x, int y) {                        // TODO Auto-generated method stub                    }                    @Override                    public int getIconWidth() {                        // TODO Auto-generated method stub                        return 0;

               Object[] options = { "保存并重新开始游戏", "不，谢谢" };                int n = JOptionPane.showOptionDialog(null, "是否保存设置并重新开始", "人机博弈设置", 0, 1, icon, options, "保存并重新开始游戏");                if (n == 0) {                    panel.setIsManAgainst(true);

3.最后设置整个游戏的入口主函数StartEntrance.java

package StartGame;import javax.swing.JFrame;public class StartEntrance {    //public static boolean canPlay =false;    public static void main(String[] args) {        // 实例化一个窗口        MyFrame myFrame = new MyFrame();        myFrame.setVisible(true); // 设置窗口为可见        myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // 设置窗口关闭操作属性    }}

以上所有代码均调试通过，人机算法较为简单，可实现简单的防守功能。
