Answer
TreeSet maintains sorted order but has higher time complexity than HashSet.
TreeSet, unlike HashSet, keeps elements in natural order or by a comparator. It is useful when sorted order is needed, such as displaying products by price. However, TreeSet operations have O(log n) complexity, which is slower than HashSet's average O(1) operations.
