In doing your tests, it seems you did not conisder the costs associated with the computation of hash codes. If you look through the code for generating  a hash code for a String object, you would notice that there...]]> Wed, 18 Aug 2010 10:06:09 -0400 Wed, 18 Aug 2010 10:06:09 -0400 Wed, 18 Aug 2010 10:06:09 -0400 Aug 18, 2010 Jegadisan Sankar Kumar 0 This is pointless http://www.theserverside.com/discussions/thread.tss?thread_id=60728 ...]]> Wed, 18 Aug 2010 09:49:36 -0400 Wed, 18 Aug 2010 09:49:36 -0400 Wed, 18 Aug 2010 09:49:36 -0400 Aug 18, 2010 James Watson 0 Java Best Practices – Vector vs ArrayList vs HashSet http://www.theserverside.com/discussions/thread.tss?thread_id=60728 ...]]> Wed, 18 Aug 2010 09:33:39 -0400 Wed, 18 Aug 2010 09:33:39 -0400 Wed, 18 Aug 2010 09:33:39 -0400 Aug 18, 2010 James Watson 0 Java Best Practices – Vector vs ArrayList vs HashSet http://www.theserverside.com/discussions/thread.tss?thread_id=60728 ...]]> Wed, 18 Aug 2010 09:24:06 -0400 Wed, 18 Aug 2010 09:24:06 -0400 Wed, 18 Aug 2010 09:24:06 -0400 Aug 18, 2010 James Watson 0 This is pointless http://www.theserverside.com/discussions/thread.tss?thread_id=60728 ...]]> Wed, 18 Aug 2010 08:15:44 -0400 Wed, 18 Aug 2010 08:15:44 -0400 Wed, 18 Aug 2010 08:15:44 -0400 Aug 18, 2010 Mario Fusco 0 This is pointless http://www.theserverside.com/discussions/thread.tss?thread_id=60728 ...]]> Wed, 18 Aug 2010 07:45:35 -0400 Wed, 18 Aug 2010 07:45:35 -0400 Wed, 18 Aug 2010 07:45:35 -0400 Aug 18, 2010 Byron Kiourtzoglou 3 This is pointless http://www.theserverside.com/discussions/thread.tss?thread_id=60728 I believe what Mario is saying is that you are comparing Apples to Oranges.

HashSet or any set implementation should not be in the testing simply because HashSet has a different sementic compared to Vectors and ArrayLists.
