Help me out !

[Daniel Washington]

I wanna create a client-server application and need to transfer various kinds of infomation
between C-S ,these infomation includes identity validation , talking and some others :
And my question is : Can i declare numbers of input streams and output streams
in a single socket connection just like " new data input stream (socket.get input strem ())"?
If yes, How can i do that ? If no , Does that mean i should create numbers of input (output)
streams for each kinds of information using numbers of socket connection ?
