How to convert intArray to ArrayList<Int> in Kotlin?

From

val array = intArrayOf(5, 3, 0, 2, 4, 1, 0, 5, 2, 3, 1, 4)

I need to convert to ArrayList<Int>

I have tried array.toTypedArray()

But it converted to Array<Int> instead

Solution

  • You can use toCollection function and specify ArrayList as a mutable collection to fill:

    val arrayList = intArrayOf(1, 2, 5).toCollection(ArrayList())
