Enum Class

A simple enum :

enum class Rainbow {
    RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, VIOLET
}

Here's a more complicated example, where each enum value has an attribute :

enum class Rainbow( val color: String ) {
    RED( "#ff0000" ),
    ORANGE( "..." ),
    YELLOW( "#ffff00" ),
    GREEN( "00ff00" ),
    BLUE( "0000ff" ),
    INDIGO( "..." ),
    VIOLET( "...")
}

Here, color is a field. We could use it like so :

for ( hue in Rainbow.values() ) {
    println( "Hue : ${hue.name()} Color : ${hue.color}" )
}

In this example hue is one of the Rainbow enum values.
