Is there an error in the tutorial?

Question

Hi everybody!
I've been reading the generics tutorial from Sun and I don't know if thre is an error or I have not understood the documentation.
That's the tutorial code snippet:
public interface List<E> {
void add(E x);
Iterator<E> iterator();
and in the method "add" the documentation says it should return a boolean but as you can see here is returned a "void". What doyou think?. Thank you in advance.

That is certainly an error. Well spotted. This is an understandable mistake bearing in mind that before the days of Lists we used Vectors whose addElement method's return type is void.
