Kotlin list of vs array of [duplicate]

Question

What is the difference of these two snippets of code? And how to decide which one to use?

var array = arrayOf(1,2,3,4,5)

and

var list = listOf(1,2,3,4,5)

With both codes I could access it by its index like this

println(array[0]) // Outputs 1  
println(list[0]) // Outputs 1

The difference is the datatype:

var array = arrayOf(1,2,3,4,5)  --> class kotlin.Array
var list = listOf(1,2,3,4,5)    --> class java.util.Arrays$ArrayList

You have to decide which data type fits your needs the best.
