Answer Posted / sreekanth madamanchi
1. Abstract classes can have implementations for some of
its members (Methods), but the interface can't have
implementation for any of its members.
2. Only an interface can extend another interface, but any
Class can extend an abstract class..
3. Class can inherit only one abstract class, but class can
implement more than one interface
4. An abstract class can contain constructors, but
interface can’t contain any constructors
5. An abstract class can’t support multiple inheritances,
but an interface can support multiple inheritances.
EX:- class A extends AbstractClass
Class A implements interface1, interface2
6. We can use various access modifiers to variables. such
as abstract, protected, internal, public in Abstract Class,
but all of the variables in an interface are implicitly
(Default) static and final.
7. An abstract class can contain abstract and non-abstract
methods, but interface contains only abstract methods. If
we declare the method without having abstract, by default
it takes that method as abstract method
