Enum

Just like in Java, enum classes in Kotlin have synthetic methods allowing to list the defined enum constants and to get an enum constant by its name. The signatures of these methods are as follows (assuming the name of the enum class is EnumClass):

EnumClass.valueOf(value: String): EnumClass
EnumClass.values(): Array<EnumClass>

The valueOf() method throws an IllegalArgumentException if the specified name does not match any of the enum constants defined in the class.

Every enum constant has properties to obtain its name and position in the enum class declaration:

val name: String
val ordinal: Int

The enum constants also implement the Comparable interface, with the natural order being the order in which they are defined in the enum class.
