How to do it...

Let's see an example of the enum class:

1. In this example, we will create an enum of directions. We will assume that there are only four of them:

enum class Direction {    NORTH,SOUTH,EAST,WEST}fun main(args: Array<String>) {    var north_direction=Direction.NORTH    if(north_direction==Direction.NORTH){        println("Going North")    }else{        println("No idea where you're going!")    }}

2. As you can see, the variable (north_direction) can just take values among the predefined constants in the enum class.

3. We can also initialize enums with default values:

enum class Direction(var value:Int) {    NORTH(1),SOUTH(2),EAST(3),WEST(4)}fun main(args: Array<String>) {    var north_direction=1    if(north_direction==Direction.NORTH.value){ println("Going North") ...
