what are the diffrences between interface and abstract class?..

Answer / cool

=>Abstract class means
1)We can have concreate methods and abstrat methods
2) We can give implementation for concreate methods.

Interfaces means
1)we could not have concreate methods.All the methods are
abstract methods implicitly.
2)And those methods allows only public access specifier
only.It wont
allow any final,static keywords with methods .

Answer / cool

=>Interface :
1. All the methods in the interface are abstract.
2. We can achieve multiple inheritance through interface.
3. All the methods in the interface should be without
Access modifier. Implicitly public.
Abstract class:
1. Abstract class may contain abstract method and non-
abstract method.
2. We can achieve only single inheritance and multi-level
inheritance.
3. Abstract methods have Access modifiers.

Answer / ravikiran

interface is a purely abstract one when we wish to
implement all the methods for different scenarios in
different places we make use of implementation of the
interface.
abstract class is the one which contains both abstract as
well as non abstarct methods,We will define this if you
want ot restrict the instantiation of the class.
