How to define a non-ordinal enum in Kotlin?

I want to define an enum that values are not ordinal, for example:

enum class States(value: Int) {
STATE_A(4),
STATE_B(5),
STATE_C(7),
STATE_D(12)
}

How can I get the value of each item? For instance **States.STATE_C** should return **7**.

You should define `value` as property (`val`) not as constructor parameter. After that it becomes accessible:

<!-- language: kotlin -->

enum class States(val value: Int) {
STATE_A(1),
STATE_B(2),
STATE_C(3),
STATE_D(4)
}
...
println(States.STATE_C.value) // prints 3


Also consider to use `ordinal`, which may be suitable in your case:

<!-- language: kotlin -->

enum class States {
STATE_A,
STATE_B,
STATE_C,
STATE_D
}
...
println(States.STATE_C.ordinal + 1) // prints 3

If you go with that approach, be careful - any change of `States` order can break your code.
