reference a local variable from string

Is there a way that I could represent a local variable name by passing a string to represent the variable name? for example something like this

val arr1 = arrayOf(1,2,3,"Apple")
val arr2: Array<Int> = Array(6,{i -> i * 2})
val arr3: Array<Int> = Array<Int>(6,{i -> i+1})
val arr4 = arrayOf<Int>(1,2,3)
for (i in 1..4){
    val arrResult = java.util.Arrays.deepToString("arr${i}")
    println(arrResult)
}

Such question usually means that you want to use dictionaries. In this case an array suffices:

fun main() {
    val arr0 = arrayOf(1,2,3,"Apple")
    val arr1: Array<Int> = Array(6,{i -> i * 2})
    val arr2: Array<Int> = Array<Int>(6,{i -> i+1})
    val arr3 = arrayOf<Int>(1,2,3)
    val arrs = arrayOf(arr0, arr1, arr2, arr3)
    for (i in 0..3) {
        val arrResult = java.util.Arrays.deepToString(arrs[i])
        println(arrResult)
    }
}
