Answer 1

Don't use Optionals for conditional logic.

They were designed, to be returned from a method to indicate a potentially absent value.

Just because you can nicely chain them into a single line doesn't mean that it's understandable. Also you literally gain nothing. The performance overhead may be significant. In the worst case N objects being created and then discarded. Just stay with your "normal" if-else chains.

Instead of finding ways to make your current code more readable, take a step back and ask yourself why you need 15-20 if-else statements. Can you split some logic up? Why do you need a getter for so many different fields with potentially different types in the first place? etc.
