Hi,
I want to receive, by tcp/ip protocol, a stream that is a message with
specific field of specific dimension (some of 2 byte, other of 4 byte
and so on......)
I want to read it byte to byte. How can I do?

This is TCP/IP client code

import java.net.*;
import java.io.*;

  public class TCPServer  {
      public static final int PORT=7777;
     public void start() throws IOException {
        ServerSocket serverSocket = new ServerSocket(PORT);

        while (true) {
            Socket socket = serverSocket.accept();

            DataInputStream is = new
DataInputStream(socket.getInputStream());
            DataOutputStream os = new
DataOutputStream(socket.getOutputStream());
            while (true) {

               byte userInput=is.readByte();

   ????????    How can I control the end of stream
?????????????

            os.close();
            is.close();
           socket.close();
          }
     }
     public static void main (String[] args) throws Exception {
           TCPServer tcpServer = new TCPServer();
           tcpServer.start();
     }
  }
