apply method

Apply.scala

    object Greet {
      def apply(name: String): String = {
        "Hello %s".format(name)
      }
    }

    // I can call apply explicitly if I want:
    Greet.apply("bob") // => "Hello bob"

    // Or I can call Greet like it is a function:
    Greet("bob") // => "Hello bob"

    ///////////////
    class Amazing {
      def apply(x: String) = "Amazing %s!".format(x)
    }

    val amazing = new Amazing()
    amazing("world")   // => Amazing world!
