基于java-socket的网络围棋设计和J2ME的推箱子手机游戏开发

JavaSocket编程实验目的：Socket编程是信息化时代必须掌握的一项技术。这次做这个Socket程序，只是简单的做了一下，了解了大致的流程。熟练掌握socket编程中的Socket类的常用方法,熟练掌握socket编程中流的使用方法实验原理基于客户机/服务器的Socket通信模型：首先在服务器端建一个ServerSocket，ServerSocketserverSocket=newServerSocket(port);其中port是你自行选择要监听的端口（最好是在1023以上）；然后在客户端建一个Socket，Socketsocket=newSocket(host,port);其中host是你要连接的服务器的IP地址，port是与服务器的监听的port相同。这样就在两方建立了一个连接。然后用一系列的输入输出流来处理通话过程即可。要想实现p2p，实际上就相当于使一个程序既是服务器又是客户端。无需两种不同的程序。当然这其中还会涉及到一点线程的问题。三、实验步骤：本实验采用的是Java语言，首先查阅了Java的Socket编程的相关资料；熟悉了解了大致的过程。开始时设计了一个一个简单的服务器/客户端程序，在命令行下运行，服务器端只是简单的自动回复，而不能做一个人工互动。服务器和客户端是独立的两个不同的程序，服务器启动界面：客户端启动并发送消息后的界面：3、在原有的基础上改进成了一个多线程的聊天下棋类的程序，设计了简单的界面，由于没有用到NAT穿透，所以只能在局域网内进行简单的交互，在本机上程序运行界面：服务器端：客户端：实验中遇到的问题本来只想用一个socket来传递聊天信息和下棋的坐标，但是实现起来过于复杂，而且在涉及到悔棋时判断起来很麻烦，因此就用了2个线程来建立2个socket分别传递聊天和坐标，实现更加方便。程序要在监听与主线程之间轮流地切换，相当于在用户与界面交互时，要保持监听过程地同时运行，这样才能实时地捕获输入流并显示出来。实验总结简单的Socket编程，实现起来不复杂，但是实际上socket经常与线程，输入输出流相结合，要考虑很多种情况，如何建立连接，终止连接，异常处理，断线处理等等附：程序中的主要函数和类//多线程的run方法，两个线程分别处理聊天信息和坐标 publicvoidrun() { try{ serverchart=newServerSocket(6312);
