Remember that variables are not garbage collected. Objects are. So it doesn't make sense to talk about whether d2 is eligible or not. The question is whether the object that d2 referenced is eligible. And that will be, as E Armitage says, when there are no other live references. When getDate() exits you're assigning the return value (a reference to that same object) to the d variable, so it's still live until the program ends.
