CompletableFuture is part of the java.util.concurrent package and provides a way to write asynchronous, non-blocking code. It enables handling of future results from computations.
You can combine results from multiple CompletableFutures using methods like thenCombine. For instance, you can add results of two asynchronous tasks effectively.
Error handling is crucial in asynchronous programming, and CompletableFuture offers methods like exceptionally() to manage exceptions and provide fallback results.
Using CompletableFuture.allOf() allows you to wait for multiple futures to complete, making it easier to manage concurrent tasks and their results.
