hi , there is very thin line separating interfaces from abstract classes.....Abstract classes are very abstract in true sense..that means...those classes contain very basic features of the classes that extend from them.So in a way abstract classes are only intended only to get rid of the duplicated code......
While Interfaces,so called 100 % abstract classes as the name suggests they represent other face of the classes which implement them.....the main aim behind the concept of interfaces is to make a class avail the feature of polymorphic usage of OO language.....
there are many differences b/w an interface and a class...like there can b only final constant variables in an interface while an abstract class can have variables of any type..........
