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")
map.put(6, "f")
val keyList = ArrayList(map.keys)
val valueList = ArrayList(map.values)
println("Key List: $keyList")
println("Value List: $valueList")
}
Output
