When should I use ReentrantLock in Java?

When should I use ReentrantLock in Java?

You should use ReentrantLock when you need more control over thread synchronization than what synchronized blocks offer.

What are the advantages of using ReentrantLock over synchronized methods?

ReentrantLock provides features like tryLock, timed lock, and the ability to interrupt threads waiting for a lock.

Can you give me an example of using ReentrantLock?

Sure! Here's a simple example:

ReentrantLock lock = new ReentrantLock();

lock.lock();
try {
    // critical section code
} finally {
    lock.unlock();
}

Are there any downsides to using ReentrantLock?

Yes, if not used properly, it can lead to deadlocks or increased complexity in your code.
