In the example above we can notice how simple is to create such a pipeline. First, we are calling the supplyAsync() method which takes a Supplier and returns a new CompletableFuture.Then we are then transforming the result to an uppercase string by calling thenApply() method. In the end, we just print the value on the console using thenAccept() that takes a Consumer as the argument.
