How to create an Empty List in Kotlin - Step by Step Examples



How to create an Empty List in Kotlin ?

Answer

To create an empty list in Kotlin, you can use the emptyList function or the mutableListOf function with no arguments.



✐ Examples

1 Create an Empty Immutable List

In this example,

  1. We use the emptyList function to create an empty immutable list of type String.
  2. The emptyList function returns an empty list.
  3. We print the list to the standard output to verify it is empty.

Kotlin Program

fun main() {
    val emptyList: List<String> = emptyList()
    println("Empty list: $emptyList")
}

Output

Empty list: []

2 Create an Empty Mutable List

In this example,

  1. We use the mutableListOf function with no arguments to create an empty mutable list of type Int.
  2. The mutableListOf function returns an empty mutable list.
  3. We print the list to the standard output to verify it is empty.

Kotlin Program

fun main() {
    val emptyMutableList: MutableList<Int> = mutableListOf()
    println("Empty mutable list: $emptyMutableList")
}

Output

Empty mutable list: []

Summary

In this tutorial, we learned How to create an Empty List in Kotlin language with well detailed examples.
