Instant messaging system through constant development, with its fast, convenient, real-time characteristics, becoming an important communication tool, get the favour of a growing number of Internet users. Instant messaging system development mainly includes two aspects: instant messaging system server client, instant messaging system design. Instant messaging system design mainly through the Socket server Socket server, the server can read and forward from the clients information, and be able to refresh the user list. Instant messaging system design mainly by the client and the server connection is established, which makes the server to communicate with the clients information. Here, the principle has been using network communication mechanism, through direct inheritance for building a multithreaded Thread class. At the same time, the use of computer network programming in the development of the basic theory of knowledge, such as TCP/IP protocol, Client/Server mode (Client/Server mode), network programming design method, etc. Using flow in network programming to achieve the exchange of information, so as to read and send information. Instant messaging system
