What is the importance of thread synchronization in Java?

Thread synchronization is crucial in Java to prevent thread interference and ensure data consistency when multiple threads access shared resources.

Can you explain how it works in practice?

Sure! In practice, synchronization can be achieved using the synchronized keyword, which allows only one thread to access a block of code or method at a time.

What are some common issues that arise without synchronization?

Without synchronization, you may encounter issues like race conditions, where the outcome depends on the sequence of thread execution, leading to unpredictable results.

Are there any alternatives to using synchronized blocks?

Yes, alternatives include using java.util.concurrent package features like ReentrantLock, which provides more flexibility than synchronized blocks.
