本文介绍了一种基于Java技术制作的聊天室客户端毕业设计项目。随着互联网的发展,网络聊天工具成为一种受欢迎的交流工具。该项目利用了Java的简单、面向对象、分布式、健壮、安全、可移植等特点,以及多线程的功能,利用计算机网络编程的基本理论知识如TCP/IP协议,客户端/服务器端模式和网络编程的设计方法。在网络编程中,对信息的读取和发送利用了流来实现信息的交换。通过使用Eclipse集成开发环境和Java语言,首先建立了系统应用原型,然后不断修正和改进原型系统,同时采用多线程、多任务的设计思想,开发出性能稳定、功能全面的服务器。该系统的功能包括服务器端和客户端界面两部分,服务器端用于接收新用户的注册和登录验证,以及进行服务器信息和用户信息的管理,客户端通过注册界面进行注册,通过登录界面使用已注册的用户名和密码登录到聊天服务器,用户通过登录验证后即可进行在线聊天。多用户的即时聊天功能必须使用Thread类来建立多线程。最终,本聊天系统采用Eclipse为基本的开发环境,用Java语言进行程序的编写,实现了客户端/服务器、多线程和聊天功能。

基于JAVA聊天室的设计与实现 Based on the Java Chat Room Design and Implementation ABSTRACT The rapid development of computer network technology, so that people can choose to communicate more and more the traditional means of communication in the velocity and reliability have been difficult to meet the needs of the people, the instant communication system has become one of the new favorites is an indispensable part. Instant communication refers to the release of information and information receiver almost at the same time to transfer requirements, a small delay system tools. Such as the commonly used QQ tools, web, MSN communication system tools.The system includes the development of a network chat server program and a network chat client program in two aspects. The former through the Socket establish a server, server can read, forwarded from client information, and can refresh the list of users. The latter by establish a connection with the server, to client and client information exchange. Which uses a local area network communication mechanism, through direct Thread class inheritance to create multiple threads. Development of the computer network programming to the basic knowledge, such as the TCP / IP protocol, client / server mode ( Client / Server mode), network programming design method. Network programming in the information read, send, is the use of flow to achieve information exchange, which is introduced to implement a systematic analysis of information flow, including some basic software engineering methods. Through the analysis of these cases, the LAN chat tools using Eclipse as the basic development environment and Java language preparation, first in a short period of time can build up the system application prototype, then, for the initial prototype system, revises and the improvement unceasingly, at the same time, multi-threading, task design, developed a stable performance, fully functional the server. The complete implementation of the function of the system. T
