Here is a beginners question. In java one sometimes uses interface to hold data-values

public interface SymbolNames {
  String BeginPackage = "BeginPackage";
  String EndPackage = "EndPackage";
  String End = "End";
}

What is the equivalent in Kotlin? When I convert the above to Kotlin it gives me an interface with a companion object. Is this the way to go?

[karelpeeters]

Either that or top-level values, yes. Or maybe this can actually be an enum?

[halirutan]

Thanks! And top-level values mean basically just putting them inside the file like

const val BeginPackage = "BeginPackage"
const val EndPackage = "EndPackage"
const val End = "End"

An enum doesn't really fits as it's really only a collection of similar things but not enumerable.

[karelpeeters]

Yup that's what I meant.

[karelpeeters]

A singleton might work too actually:

object SymbolNames {
    ...
}

@karelpeeters Yes, a singelton is what I used in the end. Thanks again.
