基于Java的即时通讯软件设计与开发

Design and Implementation of Java-based Instant Messenger

目前即时通讯工具在互联网上使用广泛，便利、易用受欢迎，结合Java语言在跨平台、安全性、多线程、网络Socket编程等方面的优点，该文设计了一个基于Java虚拟机可跨平台特性的即时通讯工具-JavaHi。文中对JavaHi即时通讯系统的体系结构、构成模块进行了分析介绍．给出了JavaHi系统的详细设计与实现过程。实验证明，该即时通讯系统简洁实用并支持在多个操作系统平台运行。

Under the background of the extensive use of the instant messenger on the Internet, this paper proposes a cross-platform instant messenger -JavaHi which is based on Java Virtual Machine, taking advantage of the platform-cross, security, multi-thread and socket pro- gramming of Java language . The paper introduces the structure, the detailed design and implementation of the JavaHi. This instant messenger has been proved to be extended easily and to be good portability, which solves the problem of operating on multi-platforms especially between Linux and Windows.
