emm... that's a pointer :) passing variables by reference or value is
neither here nor there.
"pointer - An address, from the point of view of a programming language"
(from an online computing dictionary)
references - pointers - same thing really. ("The terms "pointer" and
"reference" are generally interchangable " - same dictionary)

Yep, there are pointers... or references... java calls them references,
c/c++ calls them pointers - but they are the same thing. c lets you get at
the pointers and affect their values directly. Java stops this, but you can
still change a pointer value - just assign it to a different object!
Automatic memory management and no pointer arithmatic is what makes java so
damm nice to anyone who's used c!
