Recursive is often cleaner, sequential is often faster.

There is already a (minimal) DoubleLinkedList in the image ...

Recursivity is usually better to read, understand. However sequential is usually more efficient (but harder to implement right).

I propose this as an exercise.
Now I was not aware that we have doubleLinkedList in the system.

I do not get why DoubleLinkedList is packaged in System-Caching and not Collections-DoubleLinkedList?

Wouldn't it be better to improve the current (Double)LinkedList instead of creating new ones? DLL had some improvements recently and I am not aware that it's missing something.
