Difference between interface and abstract class [Resolved]

Hi,

difference between an interface and abstract class

In the interface all methods must be abstract; in the abstract class some methods can be concrete. In the interface no accessibility modifiers are allowed, which is ok in abstract classes.

Thanks

1.It can contain Concrete methods(methods with implementation) So in other words, Abstract class can contain methods with both implemetaion
and without implementation
2.Multiple inheritance is not possible in case of abstract class
3.Access Specifiers are been Supported in abstract class


Interface
1.Does not contain any concrete methods
2.Multiple Inheritance is possible with interface
