How to initialize an array in Kotlin with values?

Question

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?

Answer 1

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]
