Answer
.join() waits for a CompletableFuture to complete.
.join() is used to wait for a CompletableFuture to complete and retrieve its result. Unlike.get(), it does not throw a checked exception, making it a cleaner alternative when you know the future will complete successfully. This is useful in scenarios where you need to wait for a result, such as aggregating data from multiple services into a single report.
