Are interfaces automatically static?

i know interfaces by default are abtract and public. I know we do have static interfaces too...but im not sure if they are static by default. Another thing what Im sure about is you cant declare static methods in an interface.

hmmm...finally I didnt answer your question huh.... :-)

Section 8.1.2 of the Java Language Specification states, "Member interfaces ... are always implicitly static..."

Ref: http://java.sun.com/docs/books/jls/second_edition/html/jTOC.doc.html

Because they're implicitly static, nested interfaces can be implemented without an instance of the enclosing class. (Top-level interfaces are another matter. I don't see that "static" would have any meaning in that context.)
