Kotlin Program to Convert Map (HashMap) to List

import java.util.ArrayList
import java.util.HashMap

fun main(args: Array<String>) {

    val map = HashMap<Int, String>()
    map.put(1, "a")
    map.put(2, "b")
    map.put(3, "c")
    map.put(4, "d")
    map.put(5, "e")

    val keyList = ArrayList(map.keys)
    val valueList = ArrayList(map.values)

    println("Key List: $keyList")
    println("Value List: $valueList")

}
 

Output:

Key List: [1, 2, 3, 4, 5]
Value List: [a, b, c, d, e]
