In our last example of a Java method signature, if you follow the same rules as the first two examples, you can see that the method signature here iscalculateAnswer(double, int, double, double).

Their main limitation is a result of what’s also their biggest strength: the output from the previous expression needs to match the input parameters of the referenced method signature. Let’s see an example of this limitation: createBicyclesList().forEach(b -> System.out.printf( "Bike br...
resultNow(): A default method meant to be called on a CompletableFuture, which does the same as get() but does not declare any exception in its signature. This is nice if you want to stream a list of futures and get their results. exceptionNow(): A default method that returns the ex...
