Hi,

Traits are basically Scala's workaround for the JVM not supporting multiple class inheritance.

 Here is an example of traits in Scala:

trait Car {
  val brand: String
}

trait Costly{
  val cost: Int 
}

trait Milege{
  val milege: Int
}

class Audi extends Car with Shiny with Miles{
  val brand = "Audi"
  val cost = 140000
  val milege = 20
}

I hope it helps.
