Java socket programming example based on TCP protocol

• Java

This paper describes the socket programming method of Java based on TCP protocol, which is shared for your reference. The specific analysis is as follows:

The following is a one-to-one communication programming implementation. We will continue to learn the implementation of one server listening to multiple clients.

The main steps used here are as follows:

Step 1: select a specific port (e.g. 4800) create a new socket object. Step 2: construct a BufferedReader object with the system input device, which is used to receive the characters input by the system keyboard. Step 3: construct a printwriter with the output stream obtained from the socket object. Step 4: construct a corresponding BufferedReader object with the input stream obtained from the socket object, which is used to receive the information sent by the server

I understand that the socket is closed: the socket is opened first and then closed, and the socket is closed finally.

The following is the code implementation of the client:
