Interface is similar to a class which may contain method's
signature only but not bodies and it is a formal set of
method and constant declarations that must be defined by
the class that implements it.
Interfaces are useful for:
a) Declaring methods that one or more classes are expected
to implement
b)Capturing similarities between unrelated classes without
forcing a class relationship.
c)Determining an object's programming interface without
revealing the actual body of the class.
