这篇文章给大家分享的是有关Java实现五子棋游戏的方法。小编觉得挺实用的，因此分享给大家做个参考。一起跟随小编过来看看吧。

Java五子棋功能要求：

1.创建窗口和设计一个棋盘界面
2.实现鼠标点击，棋子出现，黑白棋轮流下
3.能够判断五子相连输赢
4.添加重新开始，悔棋，退出按钮功能
这个java五子棋玩法丰富，但是界面简陋，十分适合java小白上手。界面是这样子的：

代码：

import java.awt.Graphics;

import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.util.Arrays;

import javax.swing.JOptionPane;
import javax.swing.JPanel;
