以 JAVA 技术为核心，利用计算机局域网通信机制原理(例如 TCP/IP 协议、客户端/服务器端模式（ C/S 模式)、网络编程设计方法等)完成了一款适合局域网的仿 QQ 聊天系统。该系统主要由一个聊天服务器端程序和一个聊天客户端程序两块组成。前者通过 Socket 套接字建立服务器，服务器能读取、转发客户端发来的信息，并能刷新用户列表；后者通过与服务器建立连接来进行客户端与客户端的信息交流。经测试，系统工作性能稳定，基本能达到聊天功能，并实现了部分附加功能。

Based on the JAVA technology , this paper uses some techniques of computer local area network communication , such as TCP/IP protocol , client/server model ( C/S ) and network designing method , to complete an imitation QQ chat system suitable for LAN . The system is mainly composed of a chat server program and a chat client program . Through the Socket , the former es-tablishes the server which can read , forward the information to the client , and refresh the list of users . The latter can get a con-nection with the server and then the exchange of information can be made from the client to the client . After testing , the system performance becomes stable , which can achieve the chat function and realized some additional functions .
