What are the best practices for ensuring thread safety in Java?

To ensure thread safety in Java, you can use synchronized methods, locks, and concurrent collections.

Can you explain how synchronized methods work?

Synchronized methods restrict access to a method to one thread at a time, preventing concurrent execution.

What are the advantages of using locks over synchronized methods?

Locks provide more flexibility, allowing for finer control over synchronization and the ability to interrupt threads.

Are there any specific concurrent collections you recommend?

Yes, consider using ConcurrentHashMap, CopyOnWriteArrayList, and BlockingQueue for thread-safe operations.
