Java实现五子棋（附详细源码）

这篇文章主要为大家详细介绍了Java实现五子棋游戏，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

五子棋是一种两人对弈的纯策略型棋类游戏，棋具与围棋通用，是起源于中国古代的传统黑白棋种之一。发展于日本，流行于欧美。容易上手，老少皆宜，而且趣味横生，引人入胜；不仅能增强思维能力，提高智力，而且富含哲理，有助于修身养性。

前面在实现完一个JAVA的面板之后，就想着继续实现一个相较于面板更复杂一点的程序——五子棋。但是我在在搜索资料的时候，发现网上很多关于五子棋实现的博文都是一步到位，直接给个源代码，不是很适合新手学习。所以我这里打算记录一下自己实现五子棋的整个过程，大致会分为三四个阶段。今天我们先来实现第一个阶段的五子棋。同样的我们在着手写代码之前我们需要先做一些准备。
 

一个简单的JAVA小项目，主要实现的功能有：

一、下棋功能，在棋盘的交点处落子。

二、简单人机对战功能。

图示：

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() {

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。
