What is the performance of HashSet in Java?
HashSet in Java offers average time complexity of O(1) for add, remove, and contains operations due to its underlying hash table.
Are there any scenarios where HashSet performs poorly?
Yes, HashSet can perform poorly in cases of high hash collisions, which can degrade performance to O(n) in the worst case.
How does HashSet compare to TreeSet in terms of performance?
HashSet is generally faster for basic operations, while TreeSet offers sorted order but has O(log n) time complexity for operations.
What factors can affect the performance of a HashSet?
Factors include the initial capacity, load factor, and the quality of the hash function used for the stored objects.
