How does thread synchronization affect performance in Java?

Thread synchronization in Java is crucial for ensuring that multiple threads can operate safely on shared resources. However, it can introduce overhead, leading to performance bottlenecks.

What are the common synchronization mechanisms in Java?

Common synchronization mechanisms in Java include synchronized methods, synchronized blocks, and the use of locks from the java.util.concurrent package.

Can you explain 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, providing more granular control.

What are the performance implications of using locks?

Using locks can lead to contention, where multiple threads compete for the same lock, potentially causing delays. It's essential to minimize lock usage to improve performance.
