Convert an IntArray to an array of Int using Kotlin

This article explores different ways to convert an IntArray to Array<Int> using Kotlin.

1. Using for loop

The idea is to create an array of Int type and assign values to it from the given IntArray using a for-loop.

fun main() {

val ints: IntArray = intArrayOf(1, 2, 3, 4, 5)

val array: Array<Int?> = arrayOfNulls(ints.size)

for (i in ints.indices) {

array[i] = Integer.valueOf(ints[i])

}

println(array.contentToString()) // [1, 2, 3, 4, 5]

}

2. Convert To List

Another solution is to convert the specified IntArray to a list using the toList() function. Then, we can call toTypedArray() function to get an Array<Int>.
