[OT] Java vector question
(Sorry to bug the list, but you're the only Java people I know :)
If I have a Vector v, and I stuff some elements into it (I know they get
in there, because I can print them out with v.firstElement() and
v.lastElement()), shouldn't I be able to get the total number of elements
from v.elementCount?
Thanks!

public int size()

Only if you are extending Vector because this field is protected (which is a bad idea anyway).
Use the size() method instead.

Please consider asking your question (and other Java questions unrelated to
Ant development) in the JDC forums:
