SPRING -> println(" Flowers are blooming") Season . SUMMER -> println("It's hot!") Season . FALL -> println("It's getting cooler") Season . WINTER -> println("I need a coat") } In case we wanted to get the value rather than print based on the timeOfYear, we can use the below snippet of code, where we return the value and it can be returned in the overall when block val str = when ( timeOfYear ) { Season . SPRING -> "Flowers are blooming" Season . SUMMER -> "It's hot!" Season . FALL -> "It's getting cooler" Season . WINTER -> { ...
