How to use keywords as enum constants

Question

I write

   public class Vehicle {
        public enum condition {new, used, wrecked, rebuilt, restored};
    }

and it doesn't build because new is a keyword. I can change it to

public enum condition {newVehicle, used, wrecked, rebuilt, restored};

but that's clunky. Is there a way to use a keyword as an enum constant?

You can use `NEW`. And btw it is a standard naming convention to write enum constant as upper case letters. — Aniket Sahrawat, Mar 24 '19 at 13:05

Well.. You can use upper-cased enum constants

public enum Condition {
  NEW, USED, WRECKED, REBUILT, RESTORED;
};

Also, if you look at the documentation, it says

Because they are constants, the names of an enum type's fields are in uppercase letters.

Thus, even the recommendation is to name them so.

You SHOULD, or even MUST, to be more precise. – tworogue Mar 24 '19 at 13:07

The enum class should be capitalized as well. – Benjamin Urquhart Mar 24 '19 at 13:20
@BenjaminUrquhart No, only the first letter of the enum class name should be capitalized. – Dorian Gray Mar 24 '19 at 13:23
@DorianGray Capitalized != Uppercase ;) – Benjamin Urquhart Mar 24 '19 at 13:23

@BenjaminUrquhart Oh, I see. My bad. – Dorian Gray Mar 24 '19 at 13:24
