java.util.LinkedHashSet<E>
LinkedHashSet is a variant on HashSet. Its entries are kept in a doubly-linked list.
The iteration order is the order in which entries were inserted.
Null elements are allowed, and all the optional Set operations are supported.
Like HashSet, LinkedHashSet is not thread safe, so access by multiple threads must be synchronized
by an external mechanism such as Collections.synchronizedSet.
