Java Socket Communication

There are several steps to socket communication

Service side:

1. Creating the server, listening port

2. Service-side dead Loop accepts client requests

3. Get the client request and output

Client:

1. Create socket Connection Server

2. Sending data to the server

The service-side code is as follows:

 Public classServer { Public Static voidMain (string[] args)throwsIOException {createserver (); }    Private Static voidCreateserver ()throwsIOException {//1. Create a service-side socket, listening portServerSocket Server =NewServerSocket (8888); //2. The dead loop waits for the client to connectSocket client =NULL;  while(true){            //3. Get the socket that the client connects toClient =server.accept (); if(Client! =NULL) {System.out.println ("The client connection came up"); //4. Get client input and read it outBufferedReader Read =NewBufferedReader (NewInputStreamReader (Client.getinputstream ()));                System.out.println (Read.readline ());            Read.close (); }        }    }        }

The client code is as follows

 Public classClient { Public Static voidMain (string[] args)throwsIOException {createclient (); }    Private Static voidCreateClient ()throwsunknownhostexception, IOException {//Create clientSocket client =NewSocket ("127.0.0.1", 8888); //Client Connection service side//socketaddress endpoint = new Inetsocketaddress ("127.0.0.1", 8888);OutputStream OS =Client.getoutputstream (); OutputStreamWriter OSW=NewOutputStreamWriter (OS, "UTF-8")); BufferedWriter BW=NewBufferedWriter (OSW); Bw.write ("Hello");        Bw.flush ();        Os.close ();    Osw.close (); }}
