Kotlin - Find Array Elements Example

The example looks for the first and last even values in the array.
package net.javaguides.kotlin.examples

fun main(args: Array < String > ) {
    val nums = intArrayOf(1, 2, 3, 4, 5, 6, 7, 8, 9)

    val firstEven = nums.find {
        it % 2 == 0
    }
    println("The first even value is: $firstEven")

    val lastEven = nums.findLast {
        it % 2 == 0
    }
    println("The last even value is: $lastEven")
}
Output:
The first even value is: 2
The last even value is: 8
