How do I create an enum from an Int in Kotlin?

Question

I have this enum:

enum class Types(val value: Int) {     FOO(1)     BAR(2)     FOO_BAR(3) } 

How do I create an instance of that enum using an Int?

I tried doing something like this:

val type = Types.valueOf(1) 

And I get the error:

Integer literal does not conform to the expected type String

Answer 1

enum class Types(val value: Int) {     FOO(1),     BAR(2),     FOO_BAR(3);      companion object {         fun fromInt(value: Int) = Types.values().first { it.value == value }     } } 

You may want to add a safety check for the range and return null.
