Honestly Im not quite sure what that means. I figure I can use list.add(index, number) but Im not sure how to figure out where in the list will the number go...because i have no idea what the "natural order" would be. Any explanation on this would be awesome.

If not, you can always extract it to an array of double and sort it throught the Arrays.sort() method
