Kotlin List component4()

The syntax of List.component4() extension function is:

operator fun <T> List<T>.component4(): T

✐ Examples

1 Example

In this example,

  • We create a list named list1 containing the integers 10, 20, 30, 40, 50.
  • We use the component4() extension function to get the 4th element from the list.
  • The value of the 4th element is stored in element.
  • Finally, we print the value of element to standard output using println.

Kotlin Program

fun main(args: Array<String>) {
    val list1 = listOf(10, 20, 30, 40, 50);
    val element = list1.component4();
    println(element);
}

Output

40

2 Example

In this example,

  • We create a list named list1 containing the strings "apple", "banana", "cherry", "date", "elderberry".
  • We use the component4() extension function to get the 4th element from the list.
  • The value of the 4th element is stored in fruit.
  • Finally, we print the value of fruit to standard output using println.

Kotlin Program

fun main(args: Array<String>) {
    val list1 = listOf("apple", "banana", "cherry", "date", "elderberry");
    val fruit = list1.component4();
    println(fruit);
}

Output

date
