This caused the chat materials become more numerous, as the overseas ICQ system, the OICQ system that invented by Tencent Co., and so on. So we create a network chat medium just like the QQ. Java network 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 server-side 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 communicate with each other, as the chat is to provide point-to-multipoint and multi-threaded Java function to be completed by using multi-threaded chat and more point-to-multipoint, database management system with SQL Server2005 the completion and adoption of JDBC-ODBC Bridge access the database. The system built on the JAVA platform, the system design using object-oriented technology and object-oriented design principles. System uses the C / S structure, client and client-side and server-side client and send messages through Socket. The use of JAVA language, development tools using Eclipse. Design and Implementation of server-side process, the use of multi-threading
