Examples of java.util.NavigableSet.pollLast()

java.util.NavigableSet.pollLast()
Retrieves and removes the last (highest) element, or returns {@code null} if this set is empty. @return the last element, or {@code null} if this set is empty

            // should return null if the set is empty
            assertNull(ascendingSubMapEntrySet.pollLast());
