What are the best practices for using Futures in Java?

When using Futures in Java, it's important to handle exceptions properly, avoid blocking calls, and use a thread pool.

Can you explain how to handle exceptions with Futures?

Sure! You can use the get() method of the Future class, which throws an ExecutionException if the computation threw an exception.

What should I do to avoid blocking calls?

To avoid blocking, consider using CompletableFuture which allows for non-blocking asynchronous programming.

Are there any specific thread pool configurations I should use?

Yes, it's recommended to use a fixed thread pool or a cached thread pool depending on your application's needs.

Can you give an example of using CompletableFuture?

Certainly! You can create a CompletableFuture like this: CompletableFuture.supplyAsync(() -> { /* task */ }).
