What are the best practices for concurrency in Java?

What are the best practices for concurrency in Java?

Some best practices include using high-level concurrency utilities from the java.util.concurrent package, minimizing shared mutable state, and using thread-safe collections.

Can you explain why minimizing shared mutable state is important?

Minimizing shared mutable state reduces the risk of race conditions and makes your code easier to understand and maintain.

What are some high-level concurrency utilities I should know about?

Key utilities include ExecutorService for managing threads, CountDownLatch for synchronization, and ConcurrentHashMap for thread-safe collections.

How can I handle exceptions in concurrent tasks?

You can handle exceptions by using a custom ThreadFactory to catch exceptions or by using the Future.get() method to retrieve exceptions from tasks.
