摘要随着互联网的迅猛的进展,网络逐渐成了人们猎取信息的主要途径。做为传统的信息沟通工具 e-mail,因为其发送和接受消息时间相对滞后的缘故,不能满足人们迅速猎取信息的要求。即时通讯应运而生,为大众提供了一种崭新的综合的信息沟通平台。即时通讯不同于传统的通讯工具 e-mail,在于它的沟通是实时的,使得人们沟通更加便捷和快速,满足了人们迅速猎取信息的需求,以深受大众的喜爱,有着很好的进展前景。其中聊天软件就是即时通讯的具体实现。本系统建立在 JAVA 平台上,系统的设计使用了面对对象技术和面对对象的设计原则。系统采纳 C/S 结构,客户端与客户端以及客户端与服务器端之间通过 Socket 传送消息。使用 JAVA 语言编写,开发工具采纳 Eclipse。服务器端设计与实现过程中,采纳了多线程技术,可以在单个程序当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。关键字:多线程;客户机/服务器;java;socket;eclipseAbstractWith the rapid development of Internet, the network gradually becomes the main way for people to obtain information. As the traditional information communication tool e-mail, because of the relative lag of the sending and receiving messages of time reasons, cannot satisfy people quick access to information requirements. Im emerge as the times require, provides a new integrated information exchange platform for the public. Unlike traditional instant messaging communication tool e-mail, the exchange is that it is a real-time, makes people communicate more convenient and fast, satisfying the people quick access to information needs, so loved by the public, has a good development foreground. Concrete realization is instant messaging chat software.The system built on the JAVA platform, the system design using object-oriented technology and object-oriented design principles. System uses the C / S structure, client and client-side and server-side client and send messages through Socket. The use of JAVA language, devel...
