What are the best practices for using ReentrantLock in Java?

When using ReentrantLock, it's important to always use try-finally blocks to ensure locks are released properly.

Can you explain why try-finally is important?

Sure! It ensures that the lock is released even if an exception occurs, preventing deadlocks.

Are there any performance considerations I should be aware of?

Yes, while ReentrantLock offers more flexibility than synchronized blocks, it can introduce overhead, so use it judiciously.

What about using condition variables with ReentrantLock?

Condition variables allow threads to wait for certain conditions to be met, which can be very useful for complex thread interactions.
