Optimization: Array vs. Array List

[Byak@]

in my code i'm store some (~50) data and i must get(read) and set(change) it (all data every time) witn interval ~60ms
what collector for this "problem" will be best?

Arrays are slightly faster than Arraylists, which are in fact based on an underlying array, but you probably won't see any difference in performance for other reasons. Why not knock up a test app to see if there is a significant time difference?

Thanks.
the code of sub, manipulated with data so very large and manipulate with many objects also.create a test sample for this is not easy))
i think somebody (Agraham for example =)) already know about it.
