In the main method, what does GC gc1; do?

In class doStuff2, what does GC localGC do?

it creates a reference to a GC type of object, although it does not create one. It's like giving you a blank address card, saying "This WILL hold the address to a restaurant, somday"

Hi,

If you analyze reference of each object -

gc1 --> null
gc2 --> some object on heap
gc3 --> some object on heap
gc4 --> gc3

gc1 --> reference to object returned by doStuff --> create localGC (--> refer some object on heap) ---> passing same reference to doStuff2 (it does nothing with it) --> return the reference of localGC.
so overall -

gc1 --> refere to same object which localGC was assigned in dostuff method.


Garbage Collector and finalize
