Abstract class is a class that has no direct instances, but
whose descendants may have direct instances. There are case
i which it is useful to define classes for which the
programmer never intends to instantiate any objects; because
such classes normally are used as bae-classes in inheritance
hierarchies, we call such classes abstract classes These
classes cannot be used to instantiate objects; because
abstract classes are incomplete. Derived classes called
concrete classesmust define the missing pieces.
Abstract classes normally contain one or more abstract
methods or abstract properties, such methods or properties
do not provide implementations, but our derived classes must
override inherited abstract methods or properties to enable
obejcts ot those derived classes to be instantiated, not to
override those methods or properties in derived classes is
syntax error, unless the derived class also is an abstract
class.
