Re: Discover data patterns or Create data patterns?
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). -- Regards, Mukul Gandhi
