Kotlin List component2()
Syntax & Examples

Syntax of List.component2()

The syntax of List.component2() extension function is:

operator fun <T> List<T>.component2(): T

This component2() extension function of List returns 2nd 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 component2 function to get the second element of list.
The second element is stored in secondElement.
We print the second element using println.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf(1, 2, 3, 4, 5)
    val secondElement = list.component2()
    println("The second element is: \$secondElement")
}

Output

The second element is: 2

2 Example

In this example,

We create a list named list containing characters 'a', 'b', 'c', 'd'.
We use the component2 function to get the second element of list.
The second element is stored in secondElement.
We print the second element using println.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf('a', 'b', 'c', 'd')
    val secondElement = list.component2()
    println("The second element is: \$secondElement")
}

Output

The second element is: b

3 Example

In this example,

We create a list named list containing strings "apple", "banana", "cherry".
We use the component2 function to get the second element of list.
The second element is stored in secondElement.
We print the second element using println.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf("apple", "banana", "cherry")
    val secondElement = list.component2()
    println("The second element is: \$secondElement")
}

Output

The second element is: banana
