Cast or convert a list of String to a user defined object in Scala

Question

Let say I have a list of strings:

val myList: List[String] = List("A", "B", "C")

Is there a way to convert/cast this list to a user defined Object without hardcoding, something along the lines of:

case class MyClass(name1: String, name2: String, name3: String) val result: MyClass = myList.asInstanceOf[MyClass]

case class MyClass(names: List[String]) and pass the list. — sebszyller

val result: MyClass = myList match { case name1 :: name2 :: name3 :: Nil => MyClass(name1, name2, name3) case _ => MyClass("", "", "") // default case, if list has less than 3 strings }

Should have Nil not _ so it matches exactly 3 strings in the List
