(1) An abstract class may contain complete or
incomplete methods. Interfaces can contain only the
signature of a method but no body. Thus an abstract class
can implement methods but an interface can not implement
methods.
(2) An abstract class can contain fields,
constructors, or destructors and implement properties. An
interface can not contain fields, constructors, or
destructors and it has only the property's signature but no
implementation.
(3) An abstract class cannot support multiple
inheritance, but an interface can support multiple
inheritance. Thus a class may inherit several interfaces
but only one abstract class.
(4) A class implementing an interface has to
implement all the methods of the interface, but the same is
not required in the case of an abstract Class.
(5) Various access modifiers such as abstract,
protected, internal, public, virtual, etc. are useful in
abstract Classes but not in interfaces.
(6) Abstract classes are faster than interfaces
