✐ Examples

1 Iterate Over List with Index using for Loop

In this example,

We create a list named numbers with integer elements.
We use the indices property of the list to get the range of valid indices.
We iterate over the indices using a for loop and access each element using the index.
Within the loop, we print each element along with its index.

Kotlin Program

fun main() {
    val numbers = listOf(10, 20, 30, 40, 50)
    for (index in numbers.indices) {
        println("Element at index $index is: ${numbers[index]}")
    }
}

Output

Element at index 0 is: 10
Element at index 1 is: 20
Element at index 2 is: 30
Element at index 3 is: 40
Element at index 4 is: 50
