How to do it…

Let's now follow the given steps to create a 2D array in Kotlin:

1. We can create a simple 2D array in Kotlin using this syntax:

val array = Array(n, {IntArray(n)})

Here, n represents the dimension of the array. Here, we have used the Array class of Kotlin, which represents an array (specifically, a Java array when targeting the JVM platform). We have initialized the Array object by passing the size and initializer:

public inline constructor(size: Int, init: (Int) -> T)

2. Our dimension is n, and as an initializer, we are passing a 1D array, which then gives a structure of a 2D array. If you want to initialize the 2D array with a specific value, you need to pass it in the initializer. Consider this example:

Array<IntArray>(10 ...
