In most of my applications I have been using Arrays and Lists to store my objects. I usually use Arrays for a temp storage area until I am ready to put them in a List since a List is dynamic and can grow and shrink. I took a look at the Vector API and it looks very similar to that of List. Could anyone tell me if one is better than the other for storing String Objects in memory? What would be the pros and cons of Vector vs List. Thanks ------------------ Happy Coding, Gregg Bolinger

Use ArrayList if you are not concerned about access to your elements while you are processing them. Vector is synchronized. That's the major difference that I am aware of. The Vector class is also deprecated in favor of ArrayList. Bosun

If you need a synchronized data structure, I would suggest Collections.synchronizedList(new ArrayList()) in preference to a Vector. - Peter

Bosun, are you sure that the Vector class is deprecated?!? Where did you find this out? Is it marked as deprecated in JDK 1.4, because it's not in 1.3.1. Can anyone confirm? Regards, Reuben.
