Is OOP & completely avoiding implementation inheritance possible?

Question

I will choose Java as an example, most people know it, though every other OO language was working as well.

Java, like many other languages, has interface inheritance

Answer 1

To make mixins/composition easier, take a look at my Annotations and Annotation Processor:

In particular, the mixins example:

Note that it doesn't currently work if the interfaces/types being delegated to have parameterized methods (or parameterized types on the methods). I'm working on that...
