学士学位论文___基于java的聊天室客户端.doc

摘要 随着互联网的发展，网络聊天工具作为一种交流工具，已经受到网民的青睐。目前，出现了很多功能强大的聊天工具，其中应用比较广泛的有腾讯QQ、MSN-Messager等等。 这个项目是用Java技术制作的，其中Java是一种程序设计语言，它具有简单的、面向对象、分布式、健壮性、安全性、可移植性等特点，并且提供了多线程的功能，使得在一个程序里可同时执行多个小任务，开发中利用了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（Client/Server模式）、网络编程的设计方法等。在网络编程中对信息的读取、发送，是利用流来实现信息的交换，其中介绍了对实现一个系统的信息流的分析，包含了一些基本的软件工程的方法。经过分析这些情况，该局域网聊天工具采用Eclipse为基本开发环境和Java语言进行编写，首先可在短时间内建立系统应用原型，然后，对初始原型系统进行不断修正和改进，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。完整的实现系统的功能。通过本次毕业设计可以学到如何应用和实现面向对象的各种方法，如何使用Eclipse集成开发环境来创建和开发项目，从而完整的实现整个系统的功能。 关键词：客户端/服务器，多线程，聊天，socket 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 QQ,MSN - Messager are much more prevalent. This project is with Java technology produced of, which Java is a programming language, it has simple of, and-oriented object, and distributed, and robust sexual, and security, and portability, features, and provides has multithreaded of features, makes in a program in can while implementation multiple small task, development in the using has computer network programming of basic theory knowledge, as TCP/IP agreement, and client/server end mode (Client/Server mode), and network programming of design method,. Read, send to the information in network programming, is to use streams to achieve the exchange of information, which he introduced to the realization of a system of information flow analysis, contains some basic software engineering methods. After analysis of the situation, using Eclipse as a development environment and LAN chat tool written in the Java language, first of all, you can build systems application prototype in a short time, and then, to keep the initial prototype system fixes and improvements, at the same time, multithreaded, multitasking design ideas, developed a stable performance, full-featured server. Complete system functionality. This can learn how to apply for gr
