How to check if a List is Empty in Kotlin - Step by Step Examples

How to check if a List is Empty in Kotlin ?

To check if a List is empty in Kotlin, you can use the isEmpty() method of the List class.

In this example,

We create a List named myList.
We use the isEmpty() method of the List object myList to check if it is empty.
The isEmpty() method returns true if the list is empty, false otherwise.
Finally, we print the result to the standard output.

fun main() {
    val myList = listOf<Int>()
    val empty = myList.isEmpty()
    println("Is list empty: $empty")
}

Is list empty: true

In this example,

We create a non-empty List named myList.
We use the isEmpty() method of the List object myList to check if it is empty.
The isEmpty() method returns true if the list is empty, false otherwise.
Finally, we print the result to the standard output.

fun main() {
    val myList = listOf(1, 2, 3, 4, 5)
    val empty = myList.isEmpty()
    println("Is list empty: $empty")
}

Is list empty: false
