Ok, I understand the reasoning now. To recap:

Java 8 (will) have 3 types of public (or virtual) methods:

- concrete methods (only in classes)
- abstract methods (in classes and interfaces)
- default methods (only in interfaces)

- concrete methods do not have a modifier
- abstract methods have "abstract" modifier (which is implicit in interfaces)
- default methods have "default" modifier
