Java / Set and its implementations

What is LinkedHashSet in Java?

LinkedHashSet is the Hashtable and linked list implementation of the Set interface with predictable iteration order.

The linked list defines the iteration ordering, which is the order in which elements were inserted into the set. Insertion order is not affected if an element is re-inserted into the set.

LinkedHashSet is the subclass of HashSet class.
