What is the equivalent of Java Scanner in Kotlin?

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?

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 see here. This might be a simple alternative for you.

You can try something like this

val scan = Scanner(System.`in`)

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

Since "in" is a Kotlin keyword
