When should I use Atomic Variables in Java?

You should use Atomic Variables in Java when you need to ensure thread-safe operations on single variables without using synchronization.

Can you give me an example of how to use them?

Sure! For instance, you can use AtomicInteger to safely increment a counter in a multi-threaded environment like this: AtomicInteger counter = new AtomicInteger(0); counter.incrementAndGet();.

What are the benefits of using Atomic Variables over synchronized blocks?

Atomic Variables provide better performance and scalability since they avoid the overhead of locking and allow for lock-free thread-safe operations.

Are there any downsides to using them?

Yes, while Atomic Variables are great for single variable operations, they don't work well for compound actions that require multiple variables to be updated atomically.
