Extending an interface to another interface

Let's say I have 2 interfaces here, `Moveable` and `Walkable` (sorry for the bad example, but please if you have a better one kindly post it) ``` interface Runnable{ void run(); } interface Walkable extends Runnable { void walk(); } public class Human implements Walkable { } ``` And the interface `Walkable` is a subclass of `Runnable`, when the `Human` class implements the `Walkable` interface should the `Human` class provide implementations for `void walk()` from the interface `Walkable` and `void run()` from the interface `Runnable`? does the interface `Walkable` inherit the abstract method `run()` from the interface `Runnable`?
