When should I use synchronized vs unsynchronized methods?

Can you explain when to use synchronized methods in Java?

Synchronized methods are used when you want to control access to a method by multiple threads, ensuring that only one thread can execute it at a time.

What about unsynchronized methods? When should I use those?

Unsynchronized methods can be used when you don't need to control access to the method, allowing multiple threads to execute it simultaneously for better performance.

Are there any performance implications of using synchronized methods?

Yes, synchronized methods can lead to performance bottlenecks due to thread contention, so they should be used judiciously.

Can you give an example of a situation where I should use synchronized?

Sure! Use synchronized methods when updating shared resources, like a counter, to prevent inconsistent states.
