Enum and switches

Question

I have an enum (MessageType) but I am not sure how to read it on the server end.
Right now I have this statement:
in = clientSocket.getInputStream();
switch(in.read())
case MessageType.LOGIN:  System.out.println("Login"); break;
}But this does not work. What I am trying to do is construct a message on the client side where the first byte represents the message type so I know how to parse it on the server end. Am I going about this right?

Answer 1

I've changed my enum to a couple of public static final ints:
final int LOGIN = 0;
final int LOGOUT = 1;And in my client I have:
out = socket.getOutputStream();
out.write(LOGIN);
out.flush();Then in my server I create a new thread for each client. In the thread I have:
in = new DataInputStream(clientSocket.getInputStream());
try
     switch(in.readInt())
          case LOGIN:  System.out.println("Login"); break;
catch (IOException e) {
     e.printStackTrace();
}I execute the server first and it runs without errors, then I run the client on the same PC. After doing so I get the following error:
java.net.SocketException: Connection reset
     at java.net.SocketInputStream.read(Unknown Source)
     at java.net.SocketInputStream.read(Unknown Source)
     at java.io.DataInputStream.readInt(Unknown Source)
     at ClientHandler.run(ClientHandler.java:37)
Line 37 refers to my switch statement. Thanks for the help so far guys.
