IMHO the mechanism JAVA uses involves reference counting:
only a reference is passed to the method, so the methods are invoked on same
object.
But if you try to assign the reference smth, reference counting is used: new
object
is created, (or reference count of the other object is increased)
and the old object's reference count is decreased by one.
When reference count is zero, garbage collector has green light on freeing the
space
the object occupied
This technique was adopted in some class's implementation in C++
