The prefixing of the variable type is part of the
hungarian convention. Adding the scope to a variable name
was something put forward by microsoft. You'll see
these conventions in java  code , for the most part, by
those moving from VC++, C++ or VB to Java. <br><br>I
peronally don't find it useful. If I'm casually looking
through code I'm not going to have any more of a clue as
to what is actually going on by having types
prefixed to a varaible names. And when you look closer
it's pretty evident what datatype your working with
without any additional nomenclature. <br><br>As for
adding a scoping prefix I've personally hav not done
that but I could see some benefit. The only reason I
haven't is because I guess my general programming
practice. That being that when I'm writing, for example a
class, I'm either dealing with a stateful or a statless
object. If it's stateless everything is pretty much
method local while if it's stateful I'm dealing
primarily with memeber variables using a bare minimum of
local variables.<br><br>Other than the coding
conventions provided by sun there is a group of experienced
developers at Rogue Wave who put out conventions which are
generally accepted by the java community with open

architect
of the project purchased a copy of that book and
handed it to everyone on the team. I've been using it
ever since, and you'll find a lot of people who have
been using the language for a while will be as well.
