What are some common mistakes when using ThreadPoolExecutor?

What are some common mistakes when using ThreadPoolExecutor?

Some common mistakes include not properly managing the thread pool size, ignoring exceptions in tasks, and not shutting down the executor.

Can you explain why managing the thread pool size is important?

Yes, if the pool size is too small, tasks may take longer to complete. If it's too large, it can lead to resource contention and overhead.

What happens if I ignore exceptions in tasks?

Ignoring exceptions can lead to silent failures, making it difficult to debug issues and potentially causing the application to behave unexpectedly.

How should I properly shut down the executor?

You should call shutdown() to stop accepting new tasks and awaitTermination() to wait for existing tasks to complete.

Are there any best practices for using ThreadPoolExecutor?

Yes, some best practices include setting a reasonable pool size, handling exceptions properly, and using submit() instead of execute() for better error handling.
