Kotlin – List of Integers
To define a list of integers in Kotlin, call listOf()
function and pass all the integers as arguments to it.
The syntax of listOf() function is
fun <T> listOf(vararg elements: T): List<T>
listOf() function returns a read-only List.
Since, we are passing integers for elements
parameter, listOf() function returns a List<Int> object.
Example
In the following program, we will define a list of integers using listOf() function.
Main.kt
fun main(args: Array<String>) { val numbers = listOf(1, 3, 9, 16, 25, 36) print(numbers) }
Output
[1, 3, 9, 16, 25, 36]
