五子棋java程序

‘壹’ 求一个简单的java五子棋代码！！ 网上复制的别来了！

我有一个，刚刚做的。可以实现人机对战，人人对战，悔棋，禁手等操作。机器方主要采用的是a-b剪枝算法。功能很强大，代码很多。

‘贰’ 通过Java控制台程序完成一个五子棋游戏，能够实现黑白子交互下棋，程序自动判断输赢（需要完成判断输赢

‘叁’ 用JAVA做五子棋源代码

java网络五子棋

下面的源代码分为4个文件；
chessClient.java:客户端主程序。
chessInterface.java:客户端的界面。
chessPad.java:棋盘的绘制。
chessServer.java:服务器端。
可同时容纳50个人同时在线下棋，聊天。
没有加上详细注释，不过绝对可以运行，j2sdk1.4下通过。

‘肆’ JAVA五子棋程序代码分析（1）

‘伍’ 用eclipse编写一个基于java的五子棋（与电脑对弈）

基于java的五子棋：

主要功能代码如下：

importjava.awt.*;

publicMain(){

this.setBounds(100,10,1000,1000);
this.setLayout(newGridLayout(30,30));
inti,j;
for(i=0;i<=39;i++){
for(j=0;j<=39;j++){
state[i][j]=0;
value[i][j]=0;
}
}
for(i=5;i<=34;i++){
for(j=5;j<=34;j++){
point[i][j]=newJButton("");
this.add(point[i][j]);
point[i][j].addActionListener(this);
}
}
this.setVisible(true);
}
publicvoidactionPerformed(ActionEvente)

运行结果如下图所示：
