How to Iterate over Elements of List using For Loop in Kotlin?

Kotlin List – Iterate over Elements using For Loop

To iterate over elements of a List in Kotlin using for loop, use the following syntax.

for (element in list) {
    //code
}

We get to access i^th element of the list during i^th iteration of the loop.

Examples

In the following program, we will take a list of integers, and iterate over each of these elements using Kotlin For Loop.

Main.kt

fun main(args: Array<String>) {
    val numbers = listOf(1, 3, 9)
    for (number in numbers) {
        println(number)
    }
}

Output

1
3
9

Now, let us take a list of Strings, and iterate over each of the elements using for loop.

Main.kt

fun main(args: Array<String>) {
    val names = listOf("Abc", "Pqr", "Xyz")
    for (name in names) {
        println(name)
    }
}

Output

Abc
Pqr
Xyz

In this Kotlin Tutorial, we learned how to iterate over elements of a List in Kotlin, using for loop.
