IO Streams... I'm a wee bit confused here - any help appreciated.

[m.cantaloupe]

I've tried to simplify my question as much as possible, so here we go:

If the PrintWriter class accepts and OutputStream object as an
argument, then why won't this work:
serverOut = new PrintWriter(connection.getOutputStream());

Instead I am forced to use:
serverOut = new PrintStream(connection.getOutputStream());

.... but I can't figure why. Anybody care to shed some light?

Cheers,

Marc.

And we don't know the semantics of your connection object. What class
is it? What do the javadocs say about the class returned by the
getOutputStream method?

How exactly does it "not work" (it should)?

Yeah, sorry about that. 'connection' is a java.net.Socket.
'getOutputStream()' returns an 'OutputStream' object. Hence the
confusion, as PrintWriter definitely has a constructor that accepts a
PrintStream.
