Hi, thank you for suggestions.
I will try to follow your suggestions and improve the test.
I understand almost of yours and I also read the Class documentation of
BufferedReader.read().
When I was doing the test I found the BufferedReader.read() would never
stop until it read next char from socket server or throw a Exception when
socket is closed.
Returning -1 in BufferedReader.read() seems to be only worked in text file
instead socket message.
And I looked for help in the net that some guys said you might add a
method(Socket.setSoTimeout()) so the BufferedReader.read() would stop.
But this way is not satisfied neither since it would throw a exception.
