Iterate enum values using values() and valueOf in kotlin

Issue

Am a newbie here. Can anyone give an example to iterate an enum with values and valueOf methods??

This is my enum class

enum class Gender {
    Female,
    Male
}

I know we can get the value like this

Gender.Female

But I want to iterate and display all the values of Gender. How can we achieve this? Anyhelp could be appreciated

Solution

You can use values like so:

val genders = Gender.values()

Since Kotlin 1.1 there are also helper methods available:

val genders = enumValues<Gender>()

With the above you can easily iterate over all values:

enumValues<Gender>().forEach { println(it.name) }

To map enum name to enum value use valueOf/enumValueOf like so:

 val male = Gender.valueOf("Male")
 val female = enumValueOf<Gender>("Female")
