It's quite possible to hold a reference to an object of a child class, and treat it as if it is an instance of the abstract class. This is just the same as holding a reference to an object and treating it as if it is a reference to an interface which it implements. Interfaces and Abstract classes can never be constructed, but it's quite possible (and useful) to have variables with such a type.
