本例实现了一个完整的四人网络麻将游戏，该程序集服务器与客户端功能与一体。本例主要介绍了非对等的网络服务功能的建立，传输信息的序列化，建立虚拟的三维空间，绘制图形和显示位图，在内存中创建位图和绘制图形等。 -the cases to achieve a complete network of four mahjong games, the procedures set server and client functions and integration. The cases are introduced to the non-network services established, the sequence of transmission of information, the establishment of a virtual three-dimensional space, drawing and display bitmap in memory to create bitmap graphics and mapping.

用java实现的Tftp(Sftp)客户端与服务器程序。在这个程序中用到了一个“状态”的机制：客户端与服务器端在开始运行时有相同的状态，通过用户的输入或程序内部运行的机制，程序可以转到不同的状态，在不同的状态下程序实现了不同的功能 -Using java realized Tftp (Sftp) client and server program. In this procedure used a state of the mechanism: client and server-side run-time in the beginning has the same state, through user input or program running internal mechanisms, procedures can be transferred to a different state, in a different state under the procedures realize the different functions

双线程处理Socket，一个线程负责发一个负责 ，TCPDemo在具体实现时，设计了一个CTCPListener类专门用于服务器对特定TCP端口的侦听。另外，设计了一个CStreamSocket类专门用于TCP数据的传输。CStreamSocket作为基类，服务器程序从它派生出另一个类CSocketSender专门用于数据的发送，客户机程序从它派生出CSocketReceiver类专门用于数据的接收。这些类的继承结构如图3
