How to Get Array Length in Kotlin - Step by Step Examples

How to Get Array Length in Kotlin ?

To get the length of an array in Kotlin, you can use the size property of the array.

In this example,

We create an integer array named numbers with some values.
We then get the length of the array using size property of the array object numbers, and store the returned value in length variable.
Array.size property returns the length of this array.
Finally, we shall print the value in length to standard output.

fun main() {
    val numbers = intArrayOf(1, 2, 3, 4, 5);
    val length = numbers.size;
    println("Length of array is: $length");
}

Length of array is: 5

In this example,

We create a string array named colors with some values.
We then get the length of the array using size property of the array object colors, and store the returned value in length variable.
Array.size property returns the length of this array.
Finally, we shall print the value in length to standard output.

fun main() {
    val colors = arrayOf("red", "green", "blue");
    val length = colors.size;
    println("Length of array is: $length");
}

Length of array is: 3
