Oops. I actually wanted to type this:

And the following is even faster (by a hair):
Hashtable ret = new Hashtable[stuff.size()];
stuff.toArray(ret);
return ret;
because you avoid the evil typecheck.

This is more efficient:
return (Hashtable[]) stuff.toArray(new Hashtable[stuff.size()]);
because the data will be p
()];
stuff.copyInto(hashArray);
return hashArray;
Good luck,

I'm trying to write a method which returns an array of Hashtables, and in
the method, I am assembling the data as a vector, and trying to user
"toArray()" to return the data as an array.
Something like this:
private Hashtable[] getStuff() {
Vector stuff = new Vector();
Hashtable ht = new Hash
