Hi, i am a beginner in kotlin . I have a question , how can i find the data type of an array when initialized using arrayof()? for eg in this below example, i expected Integer? and Object? for cases #2 and #4

i found out about javaClass.name here : https://stackoverflow.com/questions/45165143/get-type-of-a-variable-in-kotlin/45165263

That is the java type. Java doesn't have a concept of nullability.

Try just x.javaClass (without .name) - you’ll see what you expected

[Dico]

that has the same result, you're looking for ::x.returnType

[StavFX]

has a different result for me 🤷

[StavFX]

Maybe it’s just the way things get printed in Scratch

[Dico]

it's still the same java Class therefore you are not getting the result you're looking for with nullability

[Dico]

kotlin.String! means unchecked nullability

[StavFX]

I’m talking about line 6 from my screenshot, where you can see the type is kotlin.Array<kotlin.Int?>

[Dico]

I dunno why it says that. It doesn't matter, the point is don't use a Java API if you want to discover nullability.

Left is the inferred Kotlin type while right of the equals sign is the string representation
