A small example, used for Java and C # TCP communication, Java as a client,c# as a server,server thread pool.

The main function is that the client can send data to the server, and then the server sends data to the client, disconnected;

Corresponds to the client issue request, the server gives a response.

JAVA Client:

Package com.cn.test;
Import java.net.*;

Import java.io.*;
    public class TCPClient2 {public static void main (string[] args) throws Exception {TcpClient ();
        public static void TcpClient () {String s= "";
        Socket Mysocket;
        InputStreamReader In=null;
        
        OutputStreamWriter Out=null;
            try{mysocket=new Socket ("127.0.0.1", 8002);
            in = new InputStreamReader (Mysocket.getinputstream (), "UTF8"); 
            out = new OutputStreamWriter (Mysocket.getoutputstream ());
            Enter data from the console String sendmsg = "";
            BufferedReader br = new BufferedReader (new InputStreamReader (system.in));
            System.out.println ("Enter Your Value:");


            sendmsg = Br.readline ();        Out.write (sendmsg);
              Write information to the server through out.
            Out.flush ();             
                 
             int c = 0; while ((c = in.read ()) >-1) {//System.out.print ((char)c); Information is written to the output stream by using in-reading the server.                
              Blocking state, S + = (char) c;                 
             //unless read to the information.
             SYSTEM.OUT.PRINTLN ("Customer receives server data---->" +s);
             In.close ();
             Out.close ();  
           Mysocket.close ();
           catch (IOException e) {System.out.println (e.tostring ());
 }

    }
}
