[Solved] What kind of values we can add to List type? [closed]

by


You can add:

  • references of type B
  • references of any class which is a subclass of B
  • null

However, if you get a reference out of the list, its compile-time type will always be of type B — even if the runtime type is actually a subclass, or null.
