Scala inherit parameterized constructor

Question

I have an abstract base class with several optional parameters:

abstract case class Hypothesis(
    requirement: Boolean = false,
    onlyDays:   Seq[Int] = Nil,         


        

Answer 1

If Hypothesis is an abstract class, then I'd not have a constructor for it. I'd set those parameters as abstract attributes of the abstract class.

But then, in this case you do need the override modifier.
