Question

What is the equivalent of Java Scanner in Kotlin?

I have used readLine() but I'd like to know whether it's type safe or not?

Answer 1

You can try something like this

val scan = Scanner(System.`in`)

val n = scan.nextLine().trim().toInt()

Since "in" is a Kotlin keyword

Answer 2

Kotlin reuses many existing Java libraries and it's perfectly fine to do so with Scanner. Otherwise, readLine simply uses System.in as you can observe here, which might be a simple alternative for you.
