Mixing
java extend and implements
I'm confused about the following structure, is it correct ?
public interface personne {} personne{}
public abstract class personneImpl implements
public interface admin {};
public class adminImpl extend personneImpl implements admin {}
or should it be :
public class adminImpl extend personneImpl implements admin, personne {}
Edit : the picture was just for simplification it's not a uml digram.

Since
personneImpl already implements personne you do not have to add that again to adminImpl if it extends personneImpl– Mark

No, that's not correct. An extends relation is used between stereotype and metatype in a profile definition. See p. 262 of the UML 2.5 specs. This connector shall have a solid triangle at the end. What can be seen from your drawing it is an association with a name Extends. That would result in an attribute within PersonneImp. An <<extends>> stereotyped connector is used only between UseCases.
What you probably intend to show (with respect to the 2nd code example) is a Generalization which is the equivalent to a Java extend keyword. That would have a hollow triangle where the arrow is now and have no label.
