How can I optimize the performance of a HashSet in my application?

To optimize a HashSet, consider the initial capacity and load factor. Setting these appropriately can reduce resizing.

What do you mean by initial capacity and load factor?

Initial capacity is the number of buckets in the HashSet, while the load factor determines when to resize. A lower load factor means fewer collisions.

Are there any specific methods to reduce collisions?

Yes, using a good hash function and ensuring that your keys are well-distributed can significantly reduce collisions.

What about memory usage? How can I manage that?

You can manage memory by choosing an appropriate initial capacity and load factor, and by removing unused elements regularly.
