Kotlin List last()
Syntax & Examples

Syntax of List.last()

There are 2 variations for the syntax of List.last() extension function. They are:

1.
fun <T> List<T>.last(): T

This extension function returns the last element.

2.
fun <T> List<T>.last(predicate: (T) -> Boolean): T

This extension function returns the last element matching the given predicate.


✐ Examples

1 Example

In this example,

  • We create a list of strings named list containing elements "apple", "banana", "cherry".
  • We use the last() function to get the last element of the list, which is "cherry".
  • Finally, we print the last element to standard output using println statement.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf("apple", "banana", "cherry")
    val lastElement = list.last()
    println("Last element: \$lastElement")
}

Output

Last element: cherry

2 Example

In this example,

  • We create a list of characters named list containing elements 'a', 'b', 'c', 'd', 'e'.
  • We use the last() function to get the last element of the list, which is 'e'.
  • Finally, we print the last element to standard output using println statement.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf('a', 'b', 'c', 'd', 'e')
    val lastElement = list.last()
    println("Last element: \$lastElement")
}

Output

Last element: e

3 Example

In this example,

  • We create a list of strings named list containing elements "red", "green", "blue".
  • We use the last() function to get the last element of the list, which is "blue".
  • Finally, we print the last element to standard output using println statement.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf("red", "green", "blue")
    val lastElement = list.last()
    println("Last element: \$lastElement")
}

Output

Last element: blue
