hi Uday,what you've done is, created an annonymous inner
class which is the implementer class of the interface.Here
the refernce variable is of the interface but it is
referencing to the newly created annonymous inner class
instance.
Here the instanceof operator returns true because
annonymous inner class is the implementer of interface and
instanceof always returns true with the same class or its
super class(try using instanceof with Object class, it will
always return true,may the object be of any class).
