模拟qq聊天室。

服务器端：使用TCP协议创建套接字拿到机器的IP地址，选择一个可用的端口号，绑定它们，然后侦听客户端等待套接字连接。在收到客户端的连接请求，创建一个线程来与客户端进行交互。

客户端：类似服务器端，创建一个socket，注意IP和端口号和服务器端的匹配。在发送连接请求，服务器端，输入您的用户名，然后连接服务器时，可以接收其他客户端发送的数据，但他们也可以将数据发送到服务器端，聊天室功能的实现。-Simulated qq chat rooms.

server side: using tcp protocol creates socket to get the IP address of the machine, select an available port number, bind them, and then listen for client-side waiting for the socket connection. Upon receipt of the client-side connection request, create a thread to interact with the client side.

Before sending a connection request on the server side, enter your user name, and then connect server, you can receive the data sent by other client-side, but they can also send data to the server side, the chat room feature is realized.
