java.util.NavigableSet.lower()
Returns the greatest element in this set strictly less than the given element, or {@code null} if there is no such element. @param e the value to match @return the greatest element less than {@code e}, or {@code null} if there is no such element @throws ClassCastException if the specified element cannot becompared with the elements currently in the set @throws NullPointerException if the specified element is nulland this set does not permit null elements
