Concept :

The Java TreeSet class implements the Set interface, which stores data in a tree. It implements the NavigableSet interface and inherits from AbstractSet. The TreeSet class's objects are stored in ascending order. TreeSet is accomplished using a binary search tree that, like a Red-Black Tree, is self-balancing. As a result, operations like search, delete, and add take O(log(N)) time.
