Well, first of all, running the constructor of a subclass calls the constructors of its parents, so creating an instance of a subclass makes the constructor of the abstract class run. Secondly, if you have any variable that refers to the type of the inherriting subclass, it still passes the is-a test for the tyep of the abstract parent class, so it is, implicitly an object of that type and you can use it to call abstract classs' methods and fields.
