They all must be public. Therefore, to prevent us from
getting the false impression that we have choice to access,
so we are not allowed to specify any accessibility, it's
public by default.

Answer / karans

All members of an interface is marked as public because :
1) If Private :- The members ca not be implemented into
child class (as private members are derived into child
class).
2). If Protected :- The members can not be accessed by
instance of the class implementing members of that
interface (as protected members become private into
inherited class) even the members will not be inherited
into other child classes of class implementing interface.
c). If Public :- The members can be implemented into
child classes and can be accessed by instances of that
class as well as can be inherited into child class of that
class.

So All the members of Interface are bydefault considered
as PUBLIC.

redefine all of the methods of interface in its inherited
class that implements it so all of these methods should be
publically accessible.
