In Java an array can be initialized such as:

public static final String[] MONTHS = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};

To create an array, we can use a library function arrayOf() and pass the item values to it, so that arrayOf("1", "2", "3").

You can use:

val MONTHS = arrayOf("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec")

Also you can use specialized classes to represent arrays of primitive types as ByteArray, ShortArray, IntArray.

In this case you can use:

val x: IntArray = intArrayOf(1, 2, 3)
