How to check if an Array is Empty in Kotlin - Step by Step Examples

How to check if an Array is Empty in Kotlin ?

To check if an array is empty in Kotlin, you can use the isEmpty() method.

In this example,

We create an integer array named numbers with some elements.
We check if the array is empty using the isEmpty() method and store the result in the variable isEmpty.
Finally, we print whether the array is empty or not.

fun main() {
    val numbers = intArrayOf(1, 2, 3)
    val isEmpty = numbers.isEmpty()
    println("Array is empty: $isEmpty")
}

Array is empty: false

In this example,

We create an integer array named emptyArray without any elements.
We check if the array is empty using the isEmpty() method and store the result in the variable isEmpty.
Finally, we print whether the array is empty or not.
