How to Initialize an Array in Kotlin - Step by Step Examples

How to Initialize an Array in Kotlin ?

To initialize an array in Kotlin, you can use arrayOf() or Array constructor.

In this example,

fun main() {
    val numbers = arrayOf(1, 2, 3, 4, 5)
    println("Array elements: ${numbers.joinToString()}")
}

Array elements: 1, 2, 3, 4, 5

In this example,

We initialize an array named fruits using the Array constructor with string values.
This creates an array of strings in Kotlin.
We print the array elements to the console.

fun main() {
    val fruits = Array(3) { "Apple" }
    println("Array elements: ${fruits.joinToString()}")
}

Array elements: Apple, Apple, Apple
