Arrays would always perform better than
Vector, although the difference should not be too significant. The real question is whether this performance is worth the sacrifice of not having the rich functionalities provided byVector, e.g. being dynamically growable, etc.Generally speaking you should always prefer
Listto arrays (see Effective Java 2nd Edition, Item 25, Prefer lists to arrays), but J2ME development may not give you the luxury.
