What are the different types of locks in Java?
In Java, the main types of locks are intrinsic locks (synchronized), ReentrantLock, ReadWriteLock, and StampedLock. Each has its use cases.
How does ReentrantLock differ from synchronized blocks?
ReentrantLock offers more flexibility than synchronized blocks, such as the ability to interrupt threads and try locking without blocking.
When should I use ReadWriteLock?
Use ReadWriteLock when you have a scenario with many read operations and few write operations, as it allows multiple readers.
Can you explain StampedLock?
StampedLock is a more advanced lock that provides optimistic locking and allows for greater concurrency with less contention.
Which lock is the best for performance?
It depends on your specific use case. Generally, StampedLock can offer better performance in read-heavy scenarios.
