listening socket in a new thread

[voipp]

Hi!
I have min-chat and that is part of client code:

    	final ObjectInputStream in = new ObjectInputStream(socket.getInputStream());
        final ObjectOutputStream out = new ObjectOutputStream(socket.getOutputStream());


            
            // Создаем поток для чтения с клавиатуры.
            BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in));

            Thread t = new Thread(
            		new Thread()
            		{
            			@Override
            			public void run()
            			{
            				while(! socket.isClosed())
            				{
            					
            				}
            					
            			}
            		}
            		);

                    line = in.readUTF(); // In this part socket input data can be delayed and it can be not printed to console immediately
                    System.out.println(line);

The reason why i have wrote particular thread is that program needs to listen servers socket and perform actions without delays in client code.
So, why should i make Object streams final ?
PS Feel free to offer another way to communicate with server data to print it to console immediately

Because the thread will make a thread local copy of the reference and it NEEDS to make sure that those definitions WILL NOT CHANGE.
