When should I use atomic variables in Java?

What are atomic variables in Java?

Atomic variables in Java are classes that provide a way to perform thread-safe operations on single variables without using synchronization.

When should I use them?

You should use atomic variables when you need to update a variable from multiple threads without locking, ensuring thread safety.

Can you give me an example?

Sure! For instance, you can use AtomicInteger to safely increment a counter in a multi-threaded environment.

Are there any performance benefits?

Yes, atomic variables can improve performance by reducing the overhead of synchronization, especially in high-concurrency scenarios.
