java+socket基于Windows平台的即时通讯系统设计
本系统建立在Java平台上，系统的设计使用了面向对象技术和面向对象的设计原则，使用Java语言编写，开发工具采用Eclipse。系统采用C/S结构模式，以Socket类来实现客户端和服务器之间的信息交换。在服务器端设计与实现过程中，采用了多线程技术，可以在单个程序中同时运行多个不同的线程，执行不同的任务，大大增强了程序对服务器资源的利用。在开发过程中，经过可行性分析，需求分析，概要设计，详细设计，编码，运行，测试，分析等阶段，最终完成了设计。
经过测试，本系统最终实现了注册、登陆、即时通讯、文件传输以及窗口抖动等功能。

Instant Messaging System Based On Windows Platform
Abstract: With the development of Internet network,instant messaging system is one of the most common way for computer users to communicate,through it,people can communicate more easily and more quickly.Now,the instant communication tool is no longer a simple Internet communication tool,it has become a set of interactive communication,entertainment and information management as one of the persified use of the Internet platform.
The system built on the Java platform,the design of the system uses object-oriented technology and the design’s principles of the object-oriented,it uses Java language,and uses Eclipse as development tools.The system uses C/S structure,with Socket to implement the exchange of information between the client and the server.Design and implantation of server-side process,the use of multi-threading technology,which can process in a single run at the same time a number of different threads,the implementation of different tasks,procedures greatly enhanced the use of server resources. In the development of the process,through the feasibility analysis,demand analysis,outline design,detailed design,coding,testing,operation,analysis and other stages,and finish the design at last.
Through testing,the system ultimately realize the registration,login,instant messaging,file transfer,and the jitter window function.
