What are some effective synchronization techniques in Java threading?

In Java, common synchronization techniques include using synchronized methods, synchronized blocks, and the ReentrantLock class.

Can you explain how synchronized blocks work?

Synchronized blocks allow you to specify a block of code that can only be executed by one thread at a time, reducing contention.

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, improving performance.

When should I use ReentrantLock instead of synchronized?

ReentrantLock provides more flexibility, such as try-lock functionality and the ability to interrupt threads waiting for a lock.
