What is a HashSet and how do I use it in Java?
A HashSet is a collection that contains no duplicate elements and allows for fast access. You can use it to store unique items.

Sure! You can create a HashSet in Java like this: HashSet<String> set = new HashSet<>();.
How do I add elements to the HashSet?
You can add elements using the add() method. For example: set.add("apple");.
What happens if I try to add a duplicate element?
If you try to add a duplicate, the HashSet will simply ignore it and not throw an error.
