Is the URLConnection class capable of being subclassed to create custom
protocol connections? Protocol in this case refers to ANY and ALL
protocol specified in RFC, e.g ftp, news, smtp, irc, nntp, and several
hundreds more or so....

If yes, should i use it or connect using the old fashion way of using
io/nio?

Why not choosing to use the Jakarta/Apache Commons Net libraries ? It
works very well.

I think you want a custom URLStreamHandler. See the javadoc for the URL
constructor

public URL(String protocol,
String host,
int port,
String file)
throws MalformedURLException

for configuration details.

Yes (and the built-in protocols are implemented in exactly this manner)

See <http://doc.novsu.ac.ru/oreilly/java/exp/ch09_06.htm> for a real-world
example.
(This book is still very useful, although a bit out-dated. It wrote "package
net.www.protocol" where Sun now uses "package sun.net.www.protocol")
