What are Java synchronization primitives?

What are Java synchronization primitives?

Java synchronization primitives are tools that help manage access to shared resources in concurrent programming.

Can you explain how the 'synchronized' keyword works?

The 'synchronized' keyword in Java is used to lock a method or block, ensuring that only one thread can access it at a time.

What are the differences between 'synchronized' methods and 'synchronized' blocks?

Synchronized methods lock the entire method, while synchronized blocks allow for more granular control over which part of the code is locked.

Are there any alternatives to using synchronization in Java?

Yes, alternatives include using java.util.concurrent package classes like ReentrantLock, CountDownLatch, and Semaphore.
