Asynchronous programming with Functional Java and comparison with Scala
The document discusses asynchronous programming in Java, specifically focusing on the CompletableFuture class introduced in Java 8, which offers features like running processes asynchronously and exception handling. It provides a comparison between Java's CompletableFuture and Scala's Future, highlighting similarities such as the handling of successful completions and callback methods. Additionally, it outlines various methods for combining and handling multiple CompletableFutures.
