What are some practical usage scenarios for TreeSet in Java?

TreeSet is useful for storing unique elements in a sorted order. Common scenarios include maintaining a leaderboard, managing a collection of unique items, and implementing a priority queue.

Can you give me an example of using TreeSet for a leaderboard?

Sure! You can use TreeSet to store player scores. When a player scores, you add their score to the TreeSet, which keeps the scores sorted. You can easily retrieve the top scores using methods like 'first()' and 'last()'.

What are the performance benefits of using TreeSet?

TreeSet offers O(log n) time complexity for add, remove, and contains operations, making it efficient for large datasets compared to other collections.

Are there any limitations to using TreeSet?

Yes, TreeSet requires elements to be comparable, which can lead to a ClassCastException if the elements are not comparable. Also, it has higher memory overhead compared to HashSet.
