Optional NOT as attribute

[GiuseppeBocci]

Use an Optional as an attribute of a class is a bad practice https://stackoverflow.com/questions/29033518/is-it-a-good-practice-to-use-optional-as-an-attribute-in-a-class

[ingconti]

to say all, the post suggested all the opposite.. anyway

[GiuseppeBocci]

Doesn't the answer say that Optional was intended for methods' return? Optional doesn't implement serializable and we are implementing the persistence, so is it better to not use Optional as a attribute?

[ingconti]

it says that can be very good to use, even in different cases from history of java. to answer about persistence pls send mew a snippet of code with a Sample class you want to persist, with optional, so we can discussion in little the problem outside IS project.
