May 11, 2024 4 minute read

CompletionStage is a construct introduced in Java 8, in the java.util.concurrent package, that represents that a task is completed or will complete in the future and can be used to chain asynchronous computations. It's a way to handle asynchronous tasks and operations in a more structured and efficient manner, providing better control and visibility into the completion status of these tasks and their results.
