What is the difference between lock and synchronized in Java?

Can you explain the difference between lock and synchronized in Java?

Sure! In Java, 'synchronized' is a keyword that allows a method or block to be accessed by only one thread at a time, while 'lock' is an interface that provides more advanced locking mechanisms.

What are the advantages of using lock over synchronized?

Using 'lock' provides more flexibility, such as the ability to try to acquire a lock without blocking, and it allows for more complex thread management.

Are there any performance differences between the two?

Yes, 'lock' can offer better performance in scenarios with high contention, as it allows for more granular control over thread access.

Can you give an example of when to use each?

Use 'synchronized' for simple cases where you need quick thread safety, and 'lock' for more complex scenarios requiring advanced features.
