Inheritance and implements in abstract class

[David Cuesta]

Hi all,
Somebody can explain me how that work?:
interface List extends Collection
...
public abstract class AbstractList
extends AbstractCollection
implements List
...
public class ArrayList
extends AbstractList
implements List, Cloneable, Serializable
...
why ArrayList class declare the implements keyword, don't inherit from AbstractList?

Thanks for all

ArrayList does inherit the List interface but sometimes its nicer to write these things out. That makes it much easier to follow.
