What are the best practices for thread safety in Java?

Some best practices include using synchronized blocks, leveraging the java.util.concurrent package, and avoiding shared mutable state.

Can you explain how synchronized blocks work?

Synchronized blocks in Java allow you to control access to a block of code by multiple threads, ensuring that only one thread can execute it at a time.

What is the java.util.concurrent package?

The java.util.concurrent package provides high-level concurrency utilities, including thread pools, concurrent collections, and synchronization aids.

How can I avoid shared mutable state?

You can avoid shared mutable state by using immutable objects or by encapsulating mutable state within a thread-local variable.
