Does Array<Int> always translate to Integer[] on the JVM?

Yes, if you want

int[]

you have to use

IntArray

instead.

Thanks. Is it common to use IntArray?

Common in what sense? If it fits your need than you should use it

Well, it only exists on JVM. So the general approach would be

Array<Int>

. Downside is, you have to initialise it “manually”.

In most cases a mutable list is a good substitution for an array. Only in rather rare cases arrays are better in terms of the resulting code.
