When an abstract class is subclassed, the subclass usually provides implementations for all of the
abstract methods in its parent class (E). However, if it does not, then the subclass must also be
declared abstract (B). Note: An abstract class is a class that is declared abstract-it may or may not
include abstract methods. Abstract classes cannot be instantiated, but they can be subclassed.
