Answer / shailesh
Null interfaces are just the normal interfaces. But with
these, our classes will be having some additional
functionality. Like, clone() method is not defined in
Cloneable interface but we can make it available for our
class by letting it use cloneable(allowing my class to
clone the objects or just giving permission to do so).
So, these just be treated as a marker interfaces that marks
our class with additional functionality.
