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。

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

}

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。
