What are the best practices for using async in Java?

When using async in Java, it's important to manage thread pools effectively, handle exceptions properly, and avoid blocking calls.

Can you explain how to manage thread pools?

You can use the Executors framework to create and manage thread pools. It's crucial to choose the right type of executor for your use case.

What about exception handling in async methods?

In async methods, use CompletableFuture to handle exceptions gracefully. You can use methods like handle or exceptionally.

Are there any performance considerations I should be aware of?

Yes, avoid creating too many threads, as it can lead to context switching overhead. Also, prefer non-blocking I/O when possible.
