Patch: `final' helper classes

[Tom Tromey]

I'm checking in this patch.  It makes a few internal helper classes
`final'.

2000-04-11  Tom Tromey  <tromey@cygnus.com>

	* java/util/Vector.java (VectorEnumeration): Now `final'.
	* java/util/Hashtable.java (HashtableEntry): Now `final'.
	(HashtableEnumeration): Likewise.
	* java/util/zip/ZipFile.java (ZipEnumeration): Now `final'.
	* java/text/RuleBasedCollator.java (RBCElement): Now `final'.
