Comprehensive Collection of Kotlin Examples
In this program, you will learn how to use toArray() to convert a list to an array in Kotlin, and use asList() to convert an array to a list.
fun main(args: Array<String>) {
//Vowel array list
val vowels_list: List<String> = listOf("a", "e", "i", "o", "u")
//Convert an ArrayList to an array
val vowels_array: Array<String> = vowels_list.toTypedArray()
//Print the elements of the array
vowels_array.forEach { System.out.print(it) }
}Output Result

In the above program, we define an array list called vowels_list. To convert an array list to an array, we use the toTypedArray() method.
Finally, use forEach() loop to print the elements of the array.
fun main(args: Array<String>) {
//Vowel array
val vowels_array: Array<String> = arrayOf("a", "e", "i", "o", "u")
//Convert Array to Array List
val vowels_list: List<String> = vowels_array.toList()
//Print Elements in the Array List
vowels_list.forEach { System.out.print(it) }
}Output Result

To convert an array to an array list, we used the toList() method.
This is the equivalent Java code:Java Program to Convert Array List to Array.
