2D Array in Kotlin
You are trying to put your IntArrays inside another array to make it 2-dimensional.The type of that array cannot be intArray, which is why this fails.Wrap your initial arrays with arrayOf instead of intArrayOf.
val even: IntArray = intArrayOf(2, 4, 6)val odd: IntArray = intArrayOf(1, 3, 5)val lala: Array<IntArray> = arrayOf(even, odd)
Short Answer:
// A 6x5 array of Int, all set to 0.var m = Array(6) {Array(5) {0} }Here is another example with more details on what is going on:
// a 6x5 Int array initialise all to 0var m = Array(6, {i -> Array(5, {j -> 0})})The first parameter is the size, the second lambda method is for initialisation.
