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

[kralli]

Yes, if you want int[] you have to use IntArray instead.

[Florian]

Thanks. Is it common to use IntArray?

[rkeazor]

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

[kralli]

Well, it only exists on JVM. So the general approach would be Array<Int>. Downside is, you have to initialise it “manually”.

[kralli]

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.

[Florian]

yea makes sense, thank you
