What are the best practices for thread safety in Java?

Some best practices for thread safety in Java include using synchronized blocks, leveraging the java.util.concurrent package, and avoiding shared mutable state.

Can you explain how synchronized blocks work?

Synchronized blocks in Java allow you to control access to a block of code by multiple threads, ensuring that only one thread can execute it at a time.

What is the difference between synchronized methods and synchronized blocks?

Synchronized methods lock the entire method, while synchronized blocks allow you to lock only a specific section of code, providing more granular control.

Are there any alternatives to using synchronized blocks?

Yes, alternatives include using ReentrantLock, ReadWriteLock, and other classes from the java.util.concurrent package that provide more flexibility.
