Why can?t you specify the accessibility modifier for methods
inside the interface?

Question Posted / umesh

Why can?t you specify the accessibility modifier for methods inside the interface?..

Answer / tsahi

Interfaces are designed to make sure a class which
implements them exposes a certain set of methods. Because
these methods are exposed, they must be public. therefore,
there is no point in implementing a method from an interface
which will be anything other than public. So all methods in
an interface are always public.

Why can?t you specify the accessibility modifier for methods inside the interface?..

Answer / umesh

They all must be public. Therefore, to prevent you from
getting the false impression that you have any freedom of
choice, you are not allowed to specify any accessibility,
it?s public by default.

Why can?t you specify the accessibility modifier for methods inside the interface?..

Answer / lakshmi

Methods that implement an interface must be declared public. The reason for this is that methods are implicitly public within an interface, so their implementation must also public. Also the return type and signature of the implementing method must match exactly the return type and signature specified in the interface definition.
