I am sorry if my comment would be inappropriate, but is there a reason not to
introduce "Optional<T> ifAbsent(Runnable emptyAction)" and change signature
of ifPresent to "Optional<T> ifPresent(Consumer<? super T> consumer)"?
In that case method chaining would be more natural and it will give a decent
way to have more than one simple action assigned to Optional without creating
messy java block.
Yes, this is starting to veer off topic from Optional.get().
I'll just say that a few methods have been added to Optional in Java 9:
ifPresentOrElse(), or(), and stream(). It seems pretty complete now. Please see
the Java 9 early access docs for details:
