have a look at the question in the following post

http://www.experts-exchange.com/Programming/Languages/Java/Q_22959757.html

the asker has a program that send info to server and he gets responses back from server

below are some lines from there that you are looking

 String remoteServer = "localhost";
         
        try {
            // Try connecting to the 'remote' machine on port 4445
            serverSocket = new Socket(remoteServer, 4445);
            toServer = new PrintWriter(serverSocket.getOutputStream(), true);
            fromServer = new BufferedReader(new InputStreamReader(
                                        serverSocket.getInputStream()));
        } catch (UnknownHostException e) {
            System.err.println("Don't know about host: " + remoteServer);
            System.exit(1);
        } catch (IOException e) {
            System.err.println("Couldn't get I/O for "
                               + "the connection to: " + remoteServer);
            System.exit(1);
        } // try-catch


toServer.println(balance); // send message to server
reply = fromServer.readLine();// get response from server
