How does Java's async/await affect performance?

Java doesn't have built-in async/await like JavaScript, but similar functionality can be achieved using CompletableFuture. This can improve performance by allowing non-blocking operations.

Can you explain how CompletableFuture works?

Sure! CompletableFuture is part of the java.util.concurrent package. It allows you to write asynchronous code by providing methods to run tasks in the background and handle their results when they're ready.

What are the performance benefits of using CompletableFuture?

Using CompletableFuture can lead to better resource utilization and responsiveness in applications, especially when dealing with I/O operations, as it allows other tasks to run while waiting for a result.

Are there any downsides to using it?

Yes, while CompletableFuture can improve performance, it can also introduce complexity in error handling and debugging, as asynchronous code can be harder to trace.
