Hi
I keep on flunking on Dan's tests on Collections.
Most of the tutorials / books only show the hierarchy for interfaces and for collections first level classes. However, there isn't any information for eg. where does LinkedHashSet derive from
Any idea from where to learn that? I am wondering why no one else never asked this very basic query. Am I missing something?
Thanks

Check out the Javaranch newsletter. Thomas Paul has written several articles about the Collections Framework.
