用java写一个聊天软件

1、局域网聊天软件是在LINUX系统下运行的一个应用程序，程序用c++语言编写。本程序有如下功能：用户列表自动刷新、通过TCP通信协议进行消息收发、MYsql数据库保存用户名与OO。该设计是一个简单的局域网聊天软件，适用于企业内部和实验室使用，不与互联网进行数据交换，具有高速、安全等优势。

2、本文着重介绍下列内容：对用户上下线消息通知、聊天消息收发等进行数据解析；TCP网络编程，讲述用TCP??? 创建Client和Server以及收发数据的实现；最后对本设计的具体实现方法和设计实现流程进行讲解以及程序运行分析。

3、The LAN chat tool is An application under LINUX.The application written by C++ language.This progrOO has the following functions: sending broadcast when login and exit,sending and receiving messages by the TCP communication protocol, using MYsql database to save chat messages. it is most often used to chat in enterprise and laboratory, it is working without data exchange from Internet,so it can transmit data high speed and security.

4、This OOOOO focuses on the following contents: the user online and offline message notification, chat message send and receive data OOOOysis; TCP network progrOOming, here tells the method of using TCP to create client and Server to send and receive data;Finally introduce the design method and implementation process of my graduation design and running the application.
