How do I implement a lock-free queue in Java?

How do I implement a lock-free queue in Java?

To implement a lock-free queue in Java, you can use atomic variables and compare-and-swap (CAS) operations.

Can you explain how CAS works in this context?

CAS allows you to update a variable only if it has a specific value, ensuring thread safety without locks.

What are the advantages of using a lock-free queue?

Lock-free queues reduce contention and improve performance in multi-threaded environments by avoiding blocking.

Are there any libraries in Java that provide lock-free queues?

Yes, the Java Concurrency package includes classes like ConcurrentLinkedQueue that implement lock-free algorithms.
