Answer
LinkedHashSet maintains insertion order with slightly more overhead.
LinkedHashSet combines the benefits of HashSet with a linked list to maintain the insertion order of elements. This can be useful for applications like maintaining a log of unique user actions in order. However, it has slightly higher overhead due to maintaining the order.
