Kotlin List component3()
Syntax & Examples

Syntax of List.component3()

The syntax of List.component3() extension function is:

operator fun <T> List<T>.component3(): T

This component3() extension function of List returns 3rd element from the list.

✐ Examples

1 Example

In this example,

We create a list named list containing integers from 1 to 5.
We use the component3 function to get the third element of list.
The third element is stored in thirdElement.
We print the third element using println.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf(1, 2, 3, 4, 5)
    val thirdElement = list.component3()
    println("The third element is: \$thirdElement")
}

Output

The third element is: 3

2 Example

In this example,

We create a list named list containing characters 'a', 'b', 'c', 'd'.
We use the component3 function to get the third element of list.
The third element is stored in thirdElement.
We print the third element using println.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf('a', 'b', 'c', 'd')
    val thirdElement = list.component3()
    println("The third element is: \$thirdElement")
}

Output

The third element is: c

3 Example

In this example,

We create a list named list containing strings "apple", "banana", "cherry".
We use the component3 function to get the third element of list.
The third element is stored in thirdElement.
We print the third element using println.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf("apple", "banana", "cherry")
    val thirdElement = list.component3()
    println("The third element is: \$thirdElement")
}

Output

The third element is: cherry
