tested, A

Correct is A

A =>is correct , B=> Cannot user super.y() to call interface method , this is only used to call superclass methods not interface method, so if you call default method of interface directly use y(); C=> void x() is less restrictive that method in interface, the interface methhos is marked as public abstract. D=> SAME REASON B + C E=> SAMME REASON C

A is correct

@Override public void x() { } @Override public void y() { A.super.y(); } @Override public void z() { }
