Drew,
Not sure if the part below was too clear - or I've misunderstood
something about Java.
As Ondra pointed out that there is a difference between an object, and
the variable that points to that object. I suspect that (below) you
were talking about changing the object pointed to by "a" (A) rather
than changing the value of the address stored in "a".
As I understand it, the object "a" points to (A) is the same object as
B. Therefore changing "A" will change "B". In other words, I agree with
your intended statement that changing A changes B.
Ondra would have been referring to the literal situation of you
changing "a" so it no longer points to "A".
Hope I am correct in this explanation, and haven't added confusion.

when a=b, if you change a, b will reflect this change
Never ever. Generally, the assigment changes its left side, leaving
whatever at the right of = completely unchanged.
