How can I optimize synchronization in Java?

To optimize synchronization in Java, consider using finer-grained locks, reducing lock contention, and using concurrent data structures.

What are some alternatives to synchronized blocks?

You can use ReentrantLock, ReadWriteLock, or the java.util.concurrent package for better performance.

When should I use synchronized methods instead of blocks?

Use synchronized methods for simplicity when the entire method needs to be synchronized, but prefer blocks for more control.

Can you explain lock contention and how to minimize it?

Lock contention occurs when multiple threads compete for the same lock. Minimize it by reducing the scope of synchronized blocks.
