In scala multiple inheritance, how to resolve conflicting methods with same signature but different return type?

Question

Consider the code below:

trait A {
  def work = { \"x\" }
}

trait B {
  def work = { 1 }
}

class C extends A with B {
  override def work = super[A].work
}         


        

Answer 1

You can't do that in Scala.

The way to work this around is to use the traits as collaborators

trait A {
  def work = { "x" }
}

trait B {
  def work = { 1 }
}

class C {
  val a = new A { }
  val b = new B { }

  a.work
  b.work
}
