[Java知识库]JAVA 实现《五子棋》游戏｜CSDN创作打卡

前言

五子棋是世界智力运动会竞技项目之一，是一种两人对弈的纯策略型棋类游戏，是世界智力运动会竞技项目之一，通常双方分别使用黑白两色的棋子，下在棋盘直线与横线的交叉点上，先形成5子连线者获胜。

棋具与围棋通用，起源于中国上古时代的传统黑白棋种之一。主要流行于华人和汉字文化圈的国家以及欧美一些地区，是世界上最古老的棋。

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。

用java语言实现，采用了swing技术进行了界面化处理，设计思路用了面向对象思想。

主要需求

1、对局双方各执一色棋子。

2、空棋盘开局。

3、黑先、白后，交替下子，每次只能下一子。

4、棋子下在棋盘的空白点上，棋子下定后，不得向其它点移动，不得从棋盘上拿掉或拿起另落别处。

5、黑方的第一枚棋子可下在棋盘任意交叉点上。

6、轮流下子是双方的权利，但允许任何一方放弃下子权，先形成5子连线者获胜。

主要设计

1、由于是两人的游戏，非单机版，所以要有多个客户端相互通信，这时就要用到socket 技术

2、设计socket服务端，用来维护socket客户端连接

3、设计socket客户端，用来实现五子棋逻辑和效果

4、客户端要能设置连接服务端的IP，用来连接服务端

5、客户端1创建游戏后，客户端2可以选择客户端1进行联机对战

6、游戏规则：

1. 对局双方各执一色棋子。
2. 空棋盘开局。
3. 黑先、白后，交替下子，每次只能下一子。
4. 棋子下在棋盘的空白点上，棋子下定后，不得向其它点移动，不得从棋盘上拿掉或拿起另落别处。
5. 黑方的第一枚棋子可下在棋盘任意交叉点上。
6. 轮流下子是双方的权利，但允许任何一方放弃下子权，先形成5子连线者获胜。

总结

通过此次的《五子棋》游戏实现，让我对swing的相关知识有了进一步的了解，对java这门语言也有了比以前更深刻的认识。

java的一些基本语法，比如数据类型、运算符、程序流程控制和数组等，理解更加透彻。java最核心的核心就是面向对象思想，对于这一个概念，终于悟到了一些。
