Question

I was given this little bit of code by my teacher for this weeks lab to help out and sadly it helps a bit but just not enough. In the context im in “selectedType” i’m not sure about and that’s not why i’m here. I’m here because I wanna know if someone can explain what “Airplane.Type.Fighter” could be.
Airplane is a class connected to this one. But i’m not sure if Type is another class that should be inside of Airplane or not.

Thoughts?

switch (selectedType)
{
  case Airplane.Type.Fighter:
    newPlane = new FighterJet(name, position, cboPlaneType.SelectedItem);
    break;
  case Airplane.Type.Passenger:
    int numPassengers = Utilities.getIntegerInputValue(txtNumberPassengers);
    newPlane =
    new PassengerAirplane(name, position, txtType.Text, txtFlightNumber.Text, numPassengers);
    break;
  default:
    newPlane = new Airplane(name, position);
    break;
  }

Answer 1

Well, we can only guess here. My guess is that Airplane is a property of the current class and that Airplane.Type is an enumeration with values such as FighterJet and Passenger.

As sean pointed out in the comments, it’s a good chance that it’s an inner enumeration.
