Kotlin List drop()
Syntax & Examples

Syntax of List.drop()

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

fun <T> Iterable<T>.drop(n: Int): List<T>

This drop() extension function of List returns a list containing all elements except first n elements.

✐ Examples

1 Example

In this example,

We create a list of integers list.
We use the drop function with the argument 2 to drop the first two elements from the list.
The resulting list result contains elements 3, 4, 5, 6.
Finally, we print the result list to standard output using print statement.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf(1, 2, 3, 4, 5, 6)
    val result = list.drop(2)
    print(result)
}

Output

[3, 4, 5, 6]

2 Example

In this example,

We create a list of characters list.
We use the drop function with the argument 3 to drop the first three elements from the list.
The resulting list result contains elements d.
Finally, we print the result list to standard output using print statement.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf(&quot;a&quot;, &quot;b&quot;, &quot;c&quot;, &quot;d&quot;)
    val result = list.drop(3)
    print(result)
}

Output

[d]

3 Example

In this example,

We create a list of strings list.
We use the drop function with the argument 1 to drop the first element from the list.
The resulting list result contains elements banana, mango, avocado.
Finally, we print the result list to standard output using print statement.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf(&quot;apple&quot;, &quot;banana&quot;, &quot;mango&quot;, &quot;avocado&quot;)
    val result = list.drop(1)
    print(result)
}

Output

[banana, mango, avocado]
