I'm not happy about this. JNic simply copied my answer with a different container.
I'll give it 24 hours before I contact CS to resolve this.

Sorry jimmack, I did not mean to steal your points! :-(
I just thought a Vector would be more suitable in a threaded environment since it is synchronized, and to make it simple, I used your example again, since tizay obviously is not yet a wizard in java.
Would it satisfy you, if I posted 20 points for you, or how would you like it?

Nic

Hi JNic.
If you don't mind, that would be good :-)
My comment was really for kurisuchine22. I know you can't split 20 points, but the fact that their comment showed no recognition for my contribution really annoyed me.
Thanks JNic ;-)
(BTW: I'd use add() instead of addElement(). addElement() is not deprecated (yet), but if you use add(), you can switch between other containers - like ArrayList - without changing the methods ;-))

how come you guys are fighting over my question?i dont want to cause arguments in this page.hope you understand.i'm just asking a question.:-)
It is easier to store the data in an ArrayList so that it can "grow" as you add new elements, then convert that to an array later (or better yet, just store the ArrayList in your bean).
ArrayList arr = new ArrayList();
while...
.
.
String dtn = rs2.getString("tn");
arr.add(dtn);
You don't need the "i" counter then either.
