This caused the chat materials bee more numerous, as the overseas ICQ system, the OICQ system that invented by Tencent Co., and so on. So we create a work chat medium just like the . Java work programming based on the power, the use of Java designed to prepare graduates a chat system.In general, the majority of the chat tool for client and server program in addition to serverside storage of customer data for the database, the system uses a client / server architecture model the adoption of Java provided Socket class connect client and server and between the client and server municate with each other, as the chat is to provide pointtomultipoint and multithreaded Java function to be pleted by using multithreaded chat and more pointtomultipoint, database management system with MYSQL the pletion and adoption of JDBCODBC Bridge access the database.The system built on the JAVA platform, the system design using objectoriented technology and objectoriented design principles. System uses the C / S structure, client and clientside and serverside client and send messages through Socket. The use of JAVA language, development tools using Eclipse. Design and Implementation of serverside process, the use of multithreading technology, which can process in a single run at the same time a number of different threads, the implementation of different tasks. Procedures greatly enhanced the use of server resources.Chat system will allow people to plete chat to more friends，and the system can search and add， can deal with new user registration, send messages, receive messages and so on.
