(Accumulated) sockets in Java

In the computer network lab class, I have a job on Java socket programming. Let's summarize it!

1. Create a server socket:

Serversocket S = new serversocket (12343); // The default value is on the local machine.
Socket Ss = S. Accept ();

2. Connect to the socket:
Socket = new socket ("localhost", 10000 );

3. Get the input from the other end:

Bufferedreader in = new bufferedreader (New inputstreamreader (socket. getinputstream ()));
String line = in. Readline ();

// There is no need to distinguish between the client and the server. After the connection is established, only the client and the server are used.

4. Add the following content to the socket:
Printwriter out = new printwriter (socket. getoutputstream (), true );
Out. println ("Here you are !!! ");
