I heard that assign a reference to null explicit will help gc to collect it.
Is that true?
If an object is out of scope, will it get gc quickly?

That is impossible to answer in general. However, if a reference is about to go out of scope, setting it to
nulljust before it does will almost certainly achieve nothing.On the other hand, if the reference variable is long-lived, then setting it to
nullmay be useful if the referenced object is no longer needed.
