Type parameters applied to Scala Function

Question

I am trying to understand the type parameters when applied to a function.

I would like to use Generic Types in the below method but using String and Int for my understa

Answer 1

Question: What's the difference between these 3 methods?

def myfunc1[X](f:String => X):X =
  Integer.min(1,2)

def myfunc2[Int](f:String => Int):Int =
  Integer.min(1,2)

def myfunc3[IDontGetTypeParameters](f:String => IDontGetTypeParameters):IDontGetTypeParameters =
  Integer.min(1,2)

Answer: Nothing. From the compiler's point of view they are the same, and they fail to compile for the same reason: each is defined to return the type of the type parameter but tries to return an integer (Scala.Int) instead.
