Answer Posted / Abhinaya Bhullar
{"hashset": "An implementation of the Set interface that allows null elements. HashSet does not guarantee the order of its elements, nor does it maintain any order.","treeset": "A sorted set that stores its elements in a red-black tree, which is self-balancing binary search tree that provides guaranteed log(n) time complexity for basic operations like add, remove, and contains.","difference": "HashSet does not guarantee the order of its elements, while TreeSet maintains a sorted order of its elements. HashSet allows null elements whereas TreeSet does not allow duplicate null elements."}
