Answer / guest

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.

Answer / harish

Interface is nothing but an unimplemented class. It
contains the method signatures. The method access
specifier may be abstract. The sub class should implement
all the methods, which are defined in the Interface. If
you don?t implement any method that class should be an
abstract class. Using Interface, It enforces the sub
classes to implement the same. So that, you can create an
instance of any sub class.
