You really want to know about end-of-line characters.
\n in whatever combination makes sense.
If you are reading text (or bytes containing ASCII characters) in
line mode using the
readLine( ) method,
you’ll never see the end-of-line characters, and so won’t
be cursed with having to figure out whether
\r\n appears at the end
of each line. If you want that level of detail, you have to read the
characters or bytes one at a time, using the readline methods. The
only time I’ve found this necessary is in networking code,
where some of the line-mode protocols assume that the line ending is
r\n. Even here, though, you can still work in
line mode. When writing, send a
readLine( ) and you won’t have
to deal with the characters.
outputSocket.print("HELO " + myName + "\r\n"); String response = inputSocket.readLine( );
