TCP transmission instance of Java implementation socket

This article illustrates the TCP transmission of Java implementation socket. Share to everyone for your reference. The specific analysis is as follows:

Client sends data to server

* TCP transmission, the process of client establishment.

* 1, create the TCP client socket service. The socket object is used.

* It is recommended that the object be clearly defined as soon as it is created. The host to connect to.

* 2, if the connection is established successfully, the data transfer channel has been established.

* This channel is the socket stream, is the bottom set up. Since it is a stream, it shows that there is both input and output.

* Want to input or output stream objects, you can find a socket to get.

* Getoutputstream (), and getInputStream () can be used to get two bytes of stream.

* 3, using the output stream, write the data.

* 4, close the resource.

The server receives the data sent over by the client and prints it on the console.

* Establish the TCP service side of the idea:

* 1, create the service-side socket service. Through the ServerSocket object.

* 2, the service side must provide a port, otherwise the client can not connect.

* 3, get the client object that is connected.

* 4, obtaining the socket stream from the client object to read the data sent by the client

* and print on the console.

* 5, close the resource. Close the client, turn off the service side.
