How can I use Java concurrency utilities effectively?

You can use Java concurrency utilities like ExecutorService, CountDownLatch, and Semaphore to manage threads and tasks efficiently.

Can you explain how ExecutorService works?

ExecutorService is an interface that provides a higher-level replacement for managing threads. It allows you to submit tasks for execution and manage their lifecycle.

What are the benefits of using CountDownLatch?

CountDownLatch is useful for synchronizing multiple threads. It allows one or more threads to wait until a set of operations in other threads completes.

Are there any common pitfalls when using these utilities?

Yes, common pitfalls include not shutting down the ExecutorService properly, leading to resource leaks, and mismanaging thread lifecycles.
