Generics & collections question

[Thierry Henry]

Hi,

i'm trying to create a type L that extends a List containing elements of type E.

public class ListTest<L extends List<E>, E>
{
    public void test()
    {
        // I want to be able to do smth like this
 
        L<Integer> list = new ArrayList<Integer>();
 
        L<String> vector = new Vector<String>();
    }
}

I can't create an instance in the above example.. Anyone has some pointers or an example of how to go about this?

If I'm not mistaken, this is unfortunately not possible, because of the way Java generics currently work (with type erasure).

See this from Angelika Langer's excellent Java Generics FAQ:
Can I create an object whose type is a type parameter?
