Почему после out.writeObject(message); мы не пишем в сокет НОВУЮ пустую СТРОКУ,ведь при работе с сокетами мы должны в конце запроса писать пустую строку

public void send(Message message) throws IOException{
       synchronized (out) {
           out.writeObject(message);
           //write new Line????
           out.flush();
       }
   }
