Premature optimization with JDK5. I'd say stick to the JDK classes if you can and only try to beef up space/performance if you need to. Normally I agree about evils of premature optimization. But ArrayListInt is practically a drop-in replacement for ArrayList<Integer> and I see no reason not to use it if it is supported and reliable. My test of 2 billion accesses (reads and writes) ran in 35% of the time when I used ArrayListInt vs. ArrayList<Integer>. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
