Answer Posted / naga~1417
A class implementing an interface must implement all of the
methods defined in the interface, while a class extending
an abstract class need not implement any of the methods
defined in the abstract class. Additionally, a class
extending an abstract class can implement an infinite
number of it's own methods.
Abstract class does not support Multiple Inheritance .
Interface supports Multiple Inheriatnce..
The differnce is that in interface all are public but in
abstract class u can have private and protected members
Abstract class contains the method defination of the some
methods. but Interface contains only method declaration, no
defination
