HashSet, LinkedHashSet and TreeSet are the implementations of Set interface which does not allow duplicate elements. In this tutorial we will see the differences between them. Fail-Fast Iterator is returned by HashSet, LinkedHashSet and TreeSet.

In a set, no duplicates are allowed. Every element in a set must be unique. We can simply add elements to a set, and finally we will get a set of elements with duplicates removed automatically. HashSet, LinkedHashSet and TreeSet are the implementations of Set interface which does not allow duplicate elements.

I'm not sure I'd implement List or Set for such a data structure since it differs a bit from the expectations for each of those
