Kotlin List takeLast()
Syntax & Examples

Syntax of List.takeLast()

The syntax of List.takeLast() extension function is:

fun <T> List<T>.takeLast(n: Int): List<T>

This takeLast() extension function of List returns a list containing last n elements.

✐ Examples

1 Example

In this example,

We create a list of integers named list1 with elements 1, 2, 3, 4, 5.
We use the takeLast function with an argument 3 on list1 to get the last 3 elements.
The result is a new list containing the last 3 elements of list1.
We print the result using println().

Kotlin Program

fun main(args: Array<String>) {
    val list1 = listOf(1, 2, 3, 4, 5)
    val result = list1.takeLast(3)
    println(result)
}

Output

[3, 4, 5]

2 Example

In this example,

We create a list of characters named list1 with elements 'a', 'b', 'c', 'd', 'e'.
We use the takeLast function with an argument 2 on list1 to get the last 2 elements.
The result is a new list containing the last 2 elements of list1.
We print the result using println().

Kotlin Program

fun main(args: Array<String>) {
    val list1 = listOf('a', 'b', 'c', 'd', 'e')
    val result = list1.takeLast(2)
    println(result)
}

Output

[d, e]

3 Example

In this example,

We create a list of strings named list1 with elements "apple", "banana", "cherry", "date", "elderberry".
We use the takeLast function with an argument 4 on list1 to get the last 4 elements.
The result is a new list containing the last 4 elements of list1.
We print the result using println().

Kotlin Program

fun main(args: Array<String>) {
    val list1 = listOf("apple", "banana", "cherry", "date", "elderberry")
    val result = list1.takeLast(4)
    println(result)
}

Output

[banana, cherry, date, elderberry]
