Java: Inheriting a generic class and setting its type

I have a generic Link class (to implement a linked list), as seen below: ``` class Link<T> { protected T next; public T getNext() { return next; } public void setNext(T newnext) { next = newnext; } } // end class Link ``` Now, I want another class called Card to inherit from this. ``` class Card extends Link { ... } ``` However, I want it to return a Card object for getNext(). How do I do this? Originally, the Link class was not generic, but then I had to perform a cast on getNext() every time I wanted to use it. I was having a seemingly related null pointer issue, so I wanted to clear this out of the way.
