In Java an array can be initialized such as:

int numbers[] = new int[] {10, 20, 30, 40, 50}

How does Kotlin's array initialization look like?

val numbers: IntArray = intArrayOf(10, 20, 30, 40, 50)

See Kotlin - Basic Types for details.

You can also provide an initializer function as a second parameter:

val numbers = IntArray(5) { 10 * (it + 1) }
// [10, 20, 30, 40, 50]
