What are the differences between thread pools and async in Java?

What are the differences between thread pools and async in Java?

Thread pools manage a pool of worker threads for executing tasks, while async allows non-blocking execution of tasks.

Can you explain how thread pools improve performance?

Thread pools reduce the overhead of thread creation and destruction, allowing for better resource management and faster task execution.

When should I use async instead of thread pools?

Use async for I/O-bound tasks where you want to avoid blocking threads, while thread pools are better for CPU-bound tasks.

Are there any downsides to using async?

Yes, async can lead to more complex code and potential difficulties in error handling and debugging.
