Hi Mike,
   Len's citing of your post, made me rereading your post. I have
following question.

Could you please elaborate where this scenario has a practical use
(i.e., at run-time, or within a running process/thread an ArrayList
can be treated as a LinkedList) ?

In Java, ArrayList and LinkedList both implement the List interface. I
think, in a statically typed language like Java, what you say might
not be possible. I think, in Java to implement your idea (i.e.,
swapping ArrayList and LinkedList behaviour), we can design a new type
(some form of list).
