Are defaults in JDK 8 a form of multiple inheritance in Java?

Question

A new feature coming in JDK 8 allows you to add to an existing interface while preserving binary compatibility.

The syntax is like

public interface S         


        

Answer 1

My answer to your question is: Yes, it is a form of multiple inheritance, because you can inherit behavior from different parents. What's missing is to inherit states, i. e., attributes.

Yes, but you can add getters and setters to your interface that the implementing classes then must implement. Nevertheless, the implementing classes don't inherit attributes. So, AFAICS, it's more like a trait-style solution rather than a multiple inheritance style solution.
