public class ArraySortedSet<E>
The ArraySortedSet
is an array implementation of the SortedSet
interface. This implementation has significantly lower memory overhead than TreeSet
(about 4 bytes per element vs. 40 bytes per element) and is intended to be a replacement for the use of TreeSet
for sets containing under 3000 elements.
The main drawback of the array implementation is its worst-case performance characteristics when adding or removing elements in reverse sorted order.
This implementation does not support null
elements.
