Kotlin List first and last Element Example

This example shows how to get first and the last elements of the list in Kotlin.

Kotlin List first and last elements

The example creates a list of fruits. We get the first and the last elements of the list.

package net.sourcecodeexamples.kotlin

fun main() {

    val fruits = listOf("banana", "mango", "apple", "orange")

    val w1 = fruits.first()
    println(w1)

    val w2 = fruits.last()
    println(w2)

    val w3 = fruits.findLast { w -> w.startsWith('a') }
    println(w3)

    val w4 = fruits.first { w -> w.startsWith('o') }
    println(w4)
}

Output:

banana
orange
apple
orange

We get the first element with first():

val w1 = words.first()

We get the last element with last():

val w2 = words.last()

We retrieve the last element of the list that starts with 'a' with findLast():

val w3 = words.findLast { w -> w.startsWith('a') }

We retrieve the first element of the list that starts with 'o' with first():

val w4 = words.first { w -> w.startsWith('o') }
