基于JAVA局域网聊天程序设计与实现本科毕业设计 Abstract With the development of the Internet,the chat tool as a communication tool, has been popularly accepted by netizens of all ages. At present, there are many powerful chat tools, of which Tencent , MSN-Messager are much more prevalent. Instant messaging software is necessary for every one who connects to the internet, which can not only provide you a prompt way to find friends and partners online, but can provide you the convenience of internet relay chat and information delivering. Up to now, there are about 300 million people using real-time software all over the world. As more and more corporations have focused on this market with growing potential, which has hundreds of millions of uses, the competitions among these corporations are extremely fierce The initial application of peer-to-peer network peer-to-peer, referred to as P2P is not the same as it is now. In fact, it can be regarded as a combination of different technologies and fashion trends. Below are the most important trends that have led the development of P2P technology: First of all, the integration of software engineering and new technologies led to a working dispersion trend. As a result, P2P computing was born. Then, in the past decade, it has turned fro m a single centralized system to distributed system due to the motivation of factors such as enterprise application integration. At last, with the development of the Internet, however, a comprehensive distributed computing has become an urgent need. Keywords: LAN chat P2P java 目 录 摘 要 i Abstract ii 1 绪论 1 1.1 JAVA的网络功能与编程 1 1.1.1 JAVA概述 1 1.1.2 JAVA的特点 3 1.1.3 JAVA语言在网络上的应用 6 1.2 JavaBeans技术 6 1.3 IP/TCP协议常识 6 1.4 Socket的简介 7 1.5 对等网络 8 1.5.1 对等网络发展历史 8 1.5.2 对等网络的概念 9 1.5.3 对等网络的主要系统结构 9 2 JAVA局域网聊天程序的需求分析 13 2.1 课题来源 13 2.2 需求分析 13 3 JAVA局域网聊天程序的系统分析与设计 15 3.1 JAVA局域网聊天程序的总体设计要点 15 3.2 JAVA局域网聊天程序的设计步骤及功能模块划分 15 3.3 JAVA局域网聊天程序各功能模块 16 4 JAVA局域网聊天程序的设计与实现 24 4.1 开发环境工具 24 4.2 硬件
