What is the Java CopyOnWriteArraySet class used for?

The Java CopyOnWriteArraySet class is used for creating a thread-safe set implementation. It is designed to provide a concurrent set that allows multiple threads to read and modify the set concurrently without the need for external synchronization. The class achieves this by creating a new copy of the underlying array whenever a modification operation is performed, ensuring that the original set remains unchanged and thread-safe.
