How to check if an Array is Not Empty in Kotlin - Step by Step Examples

How to check if an Array is Not Empty in Kotlin ?

To check if an array is not empty in Kotlin, you can use the isNotEmpty() method of the array.

In this example,

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

fun main() {
    val numbers = arrayOf(1, 2, 3)
    val notEmpty = numbers.isNotEmpty()
    println("Array is not empty: $notEmpty")
}

Array is not empty: true

In this example,

We create an empty array named emptyArray.
We check if the array is not empty using the isNotEmpty() method and store the result in the variable notEmpty.
Finally, we print whether the array is not empty or not.

fun main() {
    val emptyArray = emptyArray<Int>()
    val notEmpty = emptyArray.isNotEmpty()
    println("Array is not empty: $notEmpty")
}

Array is not empty: false
