Is Interface remain fully abstract after adding default method in java 1.8?

Question

Is Interface remain fully abstract after adding default method in java 1.8?

I am sorry if I was not able to state the question clearly.

Answer 1

JLS8 §9.1.1.1. (Abstract Interfaces) clearly states (emphasis mine):

Every interface is implicitly abstract. This modifier is obsolete and should not be used in new programs.

Besides that, the term "fully abstract" does not make sense to me. What should it mean? What would "partially abstract" mean? There is no concept like that.
