Kotlin ArrayList and arrayOf have different behaviour for toString() method Why would the Use case 1 (arrayOf) print the cryptic object address while ArrayList correctly understands and print the object properties.

Sorting a 2 dimensional array of objects in Kotlin I have a static 2 dimensional array of objects in a Kotlin project: class Tables { companion object{ lateinit var finalTable: Array } } It is a little clearer in Java: public class Tables { public static Object[][] finalTable; } The third element in one row of objects in the table, is a string boxed as an object.
