<p>Collections 2.0 includes a significant number of new collections, in addition to several
useful Comparator classes.</p>

</ul>
<p>These are the new Comparator classes:</p>
<ul>
<li><strong>ComparableComparator</strong> - A Comparator that compares Comparable objects.
This Comparator is useful, for example,
for enforcing the natural order in custom implementations
of SortedSet and SortedMap.</li>
<li><strong>ComparatorChain</strong> - ComparatorChain is a Comparator that wraps one or
more Comparators in sequence. The ComparatorChain
calls each Comparator in sequence until either 1)
any single Comparator returns a non-zero result
(and that result is then returned),
or 2) the ComparatorChain is exhausted (and zero is
returned). This type of sorting is very similar
to multi-column sorting in SQL, and this class
allows Java classes to emulate that kind of behaviour
when sorting a List.</li>
<li><strong>ReverseComparator</strong> - Reverses the order of another comparator.</li>
</ul>
