1.In Interface all methods must be abstract,
2.In the abstract class some methods can be concrete.
3.In the interface no accessibility modifiers are allowed,
which is ok in abstract classes.
4.In interface all the members are by-default public

1. you can inherit a abstract class but only one
but you can implement more than one interface.
