CompletableFuture is a class introduced in Java 8 that represents a future result of an asynchronous computation. It can be used to perform an operation asynchronously and to obtain its result when it’s available. The CompletableFuture class provides a wide range of methods that enable you to chain multiple computations and handle exceptions. For example, you can use the thenApply method to perform a transformation on the result of a CompletableFuture, or the exceptionally method to handle any exceptions that occur during the computation.
