I'm having trouble understanding the following syntax:

public class SortedList< T extends Comparable< ? super T> > extends LinkedList< T >

I see that class SortedList extends LinkedList. I just don't know what

T extends Comparable< ? super T>

means.

My understanding of it so far is that type T must be a type that implements Comparable...but what is "< ? super T >"?
