Conditionals
This is a pretty quick one:
Kotlin has the standard Java if / else if / else statements
val age = 12
if (age < 5) {
println("Go to kindergarten")
} else if (age == 5) {
println("Go to pre-school")
} else if (age > 5 && age <= 17) {
println("Go to grade ${age - 5}")
} else {
println("Go to college!")
}
But one nice feature is the when clause:
It feels like a mixture of switch/case and if/else with a flavor of ranges 🙂
when (age) {
0, 1, 2, 3, 4 -> println("Go to preschool")
5 -> println("Go to Kindergarten")
in 6..17 -> {
val grade = age - 5
println("Go to grade $grade")
}
else -> println("Go to college!")
}
