Examples of java.util.NavigableSet.descendingIterator()

java.util.NavigableSet.descendingIterator()
Returns an iterator over the elements in this set, in descending order. Equivalent in effect to {@code descendingSet().iterator()}. @return an iterator over the elements in this set, in descending order


        String startKey = new Integer(2).toString();
        entrySet = tm.headMap(startKey, true).entrySet();
        if (entrySet instanceof NavigableSet) {
            ascendingSubMapEntrySet = (NavigableSet) entrySet;
            iterator = ascendingSubMapEntrySet.descendingIterator();
            assertTrue(iterator.hasNext());
            assertEquals(2, ((Entry) iterator.next()).getValue());
        }
    }
