  public static void main(String args[]) throws Exception {
    String server = args[0];
    int port = Integer.parseInt(args[1]);
    double value = Double.valueOf(args[2]).doubleValue();

    Socket s = new Socket(server, port);
    OutputStream os = s.getOutputStream();
    DataOutputStream dos = new DataOutputStream(os);

    InputStream is = s.getInputStream();
    DataInputStream dis = new DataInputStream(is);
    value = dis.readDouble();
