How to set a String in a Option[String]?
Solution 1:
You can also just use Option(myValue) which will convert null to None and non-null to Some.
Solution 2:
You can wrap any object in an Option like this:
val opt = Some("foo")
Solution 3:
You can just wrap your object in Some class
val myField = Some(myValue)
Or if you dont have Anything, pass
None
Its called Option pattern

Solution 4:
If you want to convert empty string to None more universal solution is: Option(str).filter(_.nonEmpty)
