What is the performance of ReentrantLock compared to synchronized?

What is the performance of ReentrantLock compared to synchronized?

ReentrantLock generally offers better performance than synchronized in scenarios requiring high concurrency. It allows more flexibility, such as try-lock and timed lock features.

Can you explain the advantages of using ReentrantLock?

Sure! ReentrantLock provides features like fairness policies, the ability to interrupt threads waiting for a lock, and the ability to try to acquire a lock without blocking.

Are there any downsides to using ReentrantLock?

Yes, the main downside is that it requires more careful management of locks, as forgetting to release a lock can lead to deadlocks.

In what scenarios should I prefer synchronized over ReentrantLock?

You might prefer synchronized for simpler use cases where you don't need the advanced features of ReentrantLock, as it is easier to use and less error-prone.
