create enum in actionscript 3 and compare - actionscript-3

Question

I need to create some enum values, give it a default value and then compare it.
I have this enum class
public class Car
{
public static const Tesla:int = 1;
public static const Ford:int = 2;
}
How do I initiate a new Car enumn variable with a default value of "Tesla" and how do I compare the variable? I'm looking for something like this:
public var c:Car = new Car(Car.Tesla);
if (c == Car.Tesla){
// Do something
}
Edit, it is now changed to the following:
public final class Car
{
public static const Tesla:String = "tesla";
public static const Ford:String = "ford";
}
And in the mxml file:
public var c:String = Car.Tesla;
if (c == Car.Tesla){
// Do something
}

I have this enum class
Just so we're on the same page about it: that's not an enum and there are no enums in as3. The language doesn't have that feature.
How do I initiate a new Car enumn variable with a default value of "Tesla" and how do I compare the variable?
You cannot, because Car is a type and the static properties it has are of type int which is something completely different.
What you can do is this:
var c:int = Car.Tesla;
if (c == Car.Tesla){
// Do something
}
If you want to have a Car object instead, add a brand property to the class of type int, which you can then assign the value of your constants to:
var c:Car = new Car();
c.brand = Car.Tesla;
if (c.brand == Car.Tesla){
// Do something
}
You could also add a parameter to the constructor and insert the value there.
Btw. changing
public static const Tesla:int = 1;
to
public static const Tesla:String = "tesla";
will give you the chance to get more meaningful values during debugging. The built in constants like MouseEvent.CLICK are defined this way.
