Default and parameterized constructors
The primary constructor for any class defined in Scala is the body itself. It means that whatever you declare and define inside a class body gets instantiated when you make an instance of it. There are other ways to define secondary/auxiliary constructors as well. Take a look at the following case classes:
import java.time.LocalDate case class Employee(name: String, id: String, contact: String, email: String) case class StartUp(name: String, founder: Employee, coFounders: Option[Set[Employee]], members: Option[List[Employee]], foundingDate: Option[LocalDate])
We can see two case classes named Employee and StartUp. You may wonder why Employee is specific to our StartUp class. The StartUp case class takes a few attributes such as founder, coFounder, members, and foundingDate. So, for creating instances of these case classes, we have to provide values for each member.
