public class HashSetExample
extends Object

HashSet Demonstration

Demonstrates fundamental operations on a HashSet, including element addition, structural removal, and presence verification.

A HashSet is backed by a hash table structure. It enforces mathematical set properties by preventing duplicate entries and makes no mathematical or structural guarantees regarding the iteration order of its elements.

Complexity

• Time Complexity: O(1) amortized average time for add, remove, and contains operations, assuming a uniform hash distribution function. In the theoretical worst-case scenario (severe hash collisions), this can degrade to O(N).
• Space Complexity: O(N) required to store the elements and the underlying bucket arrays.
