Answer Posted / nanthinikrishnan
An abstract class can have concrete method, which is not
allowed in an interface. Abstract class can have private or
protected methods and variables and only public methods and
variables are allowed in interface. We can implement more
than one interface , but we can extend only one abstract
class. Interfaces provides loose coupling where as abstract
class provides tight coupling.
