An abstract class has protected and public abstract methods. For compatibility with older versions of the Java platform, it is permitted but discouraged, as a matter of style, to redundantly specify the abstract modifier for methods declared in interfaces. It is permitted, but strongly discouraged as a matter of style, to redundantly specify the public modifier for interface methods. No, Java doesn't support abstract variables.
