What are the performance differences between synchronized and Lock in Java?

What are the performance differences between synchronized and Lock in Java?

The main difference lies in flexibility and performance. 'synchronized' is simpler but can lead to thread contention, while 'Lock' provides more control and can improve performance in concurrent scenarios.

Can you explain how Lock can improve performance?

Sure! 'Lock' allows for more advanced features like tryLock(), which can help avoid blocking threads, and it also supports fairness policies.

Are there any downsides to using Lock?

Yes, while 'Lock' offers more control, it requires careful management to avoid issues like deadlocks and can be more complex to implement.

When should I use synchronized instead of Lock?

Use 'synchronized' for simpler cases where you don't need advanced features. It's easier to implement and sufficient for many scenarios.
