interface has only public method . we cat't put default or protected method in interface.it may be possiable when we design a application some method of a class may be default or protected according to my application requirment.in such case as we can't put such method in interface so why we can't defaut or protected method in interface

The purpose of an interface is to define the public API of a type; i.e., the public contract which an implementation must fulfill. More restrictive method access qualifiers don't belong in an interface declaration. You can use an abstract class for that.
