Convert Set to Array in Kotlin

In Kotlin Set has a function called toArray() which converts a Set to an Array. See in below example we are creating a set of values: "a", "b", "c" and we should expect an array of same values.

import java.util.*

fun main(args: Array<String>) {

    val set = HashSet<String>()
    set.add("a")
    set.add("b")
    set.add("c")

    val array = arrayOfNulls<String>(set.size)
    set.toArray(array)

    println("Array: ${Arrays.toString(array)}")

}

Output

Set: [a, A, b, c]
