What is the difference between ReentrantLock and synchronized?

What is the difference between ReentrantLock and synchronized in Java?

ReentrantLock is a more flexible locking mechanism compared to synchronized. It allows for features like try-lock and timed lock.

Can you explain the advantages of using ReentrantLock?

Sure! ReentrantLock provides better control over locking, allows for interruptible locks, and can be used in a more complex locking strategy.

Are there any downsides to using ReentrantLock?

Yes, the main downside is that it requires more code to manage the lock and unlock process, which can lead to potential errors if not handled properly.

When should I use synchronized instead of ReentrantLock?

Use synchronized for simpler scenarios where you need basic locking without the overhead of managing a ReentrantLock.
