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

How to Declare an Array in Kotlin ?

To declare an array in Kotlin, you can use the array creation functions like arrayOf(), intArrayOf(), or emptyArray().

In this example,

We declare an integer array named numbers using intArrayOf() function and initialize it with some values.
This function creates and returns an array of integers.
We print the array elements to the standard output.

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

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

In this example,

We declare a string array named fruits using arrayOf() function and initialize it with some string values.
This function creates and returns an array of strings.
We print the array elements to the standard output.

fun main() {
    val fruits = arrayOf("Apple", "Banana", "Orange")
    println("Array elements: ${fruits.joinToString()}")
}

Array elements: Apple, Banana, Orange
