Kotlin .indices

In Kotlin, the .indices property returns a range indicating the valid indices in an array.

Syntax

arr.indices

• arr: The array whose valid indices are to be accessed.

Example

The following example demonstrates the usage of the .indices property:

fun main() {
  // Creating an array
  val arr = intArrayOf(1, 6, 12, 18, 24, 30)

  // Using the '.indices' property
  val num = arr.indices

  // Printing the result
  println("$num")
}
