What is the Java Executor Framework and CompletableFuture?

Can you explain the Java Executor Framework and how CompletableFuture works?

Sure! The Java Executor Framework is a high-level API for managing threads and asynchronous tasks. CompletableFuture is a part of this framework that allows you to write non-blocking code and handle asynchronous computations.

What are the benefits of using CompletableFuture over traditional threading?

CompletableFuture provides a more flexible and powerful way to handle asynchronous programming. It allows for better composition of tasks, easier error handling, and can be combined with lambda expressions for cleaner code.

Can you give me an example of using CompletableFuture?

Absolutely! Here's a simple example: you can create a CompletableFuture that runs a task asynchronously and then use the thenApply method to process the result once it's complete.

What happens if a CompletableFuture fails?

If a CompletableFuture fails, you can handle the exception using the handle or exceptionally methods, allowing you to define fallback logic.
