Answer / sunitha
Interface - All Methods in the Interface are abstract
Methods.So the Access Modifier is public by default which
helps the Class ABC Implementing the Interface to define
the code for the methods
Abstract - > Protected Methods can be defined & implemented
in Abstract Class. This class does some implementation of
its own & leaves the remaining implementation to the
Derived Class
1.Multiple Inheritance is possible through Interface only.
2.If we add any new method in the interface, then all the
derived class has to be altered to include the
implementation of the method.
3.Interface is on the Top Level

Answer / guest
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.
