What are some examples of thread synchronization in Java?

In Java, thread synchronization can be achieved using various techniques. Some common examples include using the synchronized keyword, Lock interfaces, and Semaphore classes.

Can you explain how the synchronized keyword works?

The synchronized keyword in Java is used to lock a method or a block of code, ensuring that only one thread can access it at a time. This prevents thread interference and memory consistency errors.

What is the difference between synchronized methods and synchronized blocks?

Synchronized methods lock the entire method, while synchronized blocks allow you to lock only a specific section of code. This provides more granular control over synchronization.

Are there any performance implications of using synchronization?

Yes, excessive use of synchronization can lead to performance bottlenecks due to thread contention. It's important to use it judiciously to maintain efficiency.
