Language.scala

trait Language {
  def lang(): Unit
}

trait Functional extends Language {
  override def lang() {
    println("Functional")
  }
}

trait ObjectOriented extends Language {
  override def lang() {
    println("ObjectOriented")
  }
}

class Scala extends Functional with ObjectOriented
new Scala().lang() // output --> ObjectOriented

class Scala extends ObjectOriented with Functional
new Scala().lang() // output --> Functional
