What is the difference between HashSet and TreeSet ?
Answer
The HashSet is Implemented using a hash table and thus, its elements are not ordered. The add, remove, and contains methods of aHashSet have constant time complexity O(1).
On the other hand, a TreeSet is implemented using a tree structure. The elements in a TreeSet are sorted, and thus, the add, remove, and contains methods have time complexity of O(logn).
