How does a HashSet store elements?

  1. In a linked list

  2. Using a hashing technique

  3. In insertion order

  4. In ascending order

The correct answer is: Using a hashing technique

A HashSet uses a hashing technique to store elements in a way that allows for efficient retrieval of data. The data is stored in an array-like structure called a hash table. Each element is assigned a unique location in the hash table based on its hash code. This allows for fast lookup and retrieval of data. Options A, C, and D are incorrect because HashSet does not use a linked list, insertion order, or ascending order to store elements.
