import java.util.Date

class Console(val make:String, val model:String, val debut:Date,
  val wifi_type:Option[String], val formats:List[String], val resolution:Int) {

  override def toString = s"make: $make, model: $model, debut: $debut, " +
  s"wifi type: $wifi_type, formats: $formats, resolution: $resolution"
}

val c = new Console("make0", "model0", new Date(), Option("b/g"),
  List("format0", "format1"), 10)
println(c)
