What is the difference between thread synchronization and locks in Java?

What is the difference between thread synchronization and locks in Java?

Thread synchronization is a mechanism to control access to shared resources by multiple threads, ensuring data consistency. Locks, on the other hand, are specific tools used to implement synchronization, allowing only one thread to access a resource at a time.

Can you explain how locks work in Java?

In Java, locks are implemented using the Lock interface, which provides methods like lock() and unlock(). When a thread calls lock(), it acquires the lock, preventing other threads from accessing the locked resource until it calls unlock().

Are there different types of locks in Java?

Yes, Java provides several types of locks, including ReentrantLock, ReadWriteLock, and StampedLock, each serving different use cases for thread management.

When should I use synchronization instead of locks?

Use synchronization when you need a simple way to control access to a method or block of code. Locks are more flexible and provide advanced features, so use them when you need more control over thread behavior.
