How can I get a random number in Kotlin?

Question

A generic method that can return a random integer between 2 parameters like ruby does with rand(0..n).

Any suggestion?

Answer 1

To get a random Int number in Kotlin use the following method:

import java.util.concurrent.ThreadLocalRandom

fun randomInt(rangeFirstNum:Int, rangeLastNum:Int) {
    val randomInteger = ThreadLocalRandom.current().nextInt(rangeFirstNum,rangeLastNum)
    println(randomInteger)
}
fun main() {    
    randomInt(1,10)
}


// Result – random Int numbers from 1 to 9

Hope this helps.
