Java 9 Interface vs Class

Question

Private methods are not inherited by subclasses, so this feature doesn't affect implementation classes. I believe the private methods in interfaces allow us to share code between default methods.

Java interfaces still cannot have non-static members. That's a big difference and not multiple inheritance IMO.
