Access static field from Java superclass

Question

I have a Kotlin class that extends a Java class.

Kotlin

class MyKotlinClass: MyJavaClass() {

    companion object {
        const val STATUS_SUB = 1
    }
}

Java

public abstract class MyJavaClass {

    public static final int STATUS_SUPER = 0

}

How can I access the super class field through the kotlin subclass?

Kotlin

when(status) {
    MyKotlinClass.STATUS_SUPER -> something()
    MyKotlinClass.STATUS_SUB -> somethingElse()
}

Is this possible? It says "unresolved reference: STATUS_SUPER" Would it be possible without using MyJavaClass.STATUS_SUPER?

Try

MyJavaClass.STATUS_SUPER

Since STATUS_SUPER is not a member of MyKotlinClass you won't be able to access it.

is it possible without referring the super class? – dumazy Oct 17 '17 at 08:58

No, because `static` members can't be inherited. Inheritance only works on instances. – Adam Arold Oct 17 '17 at 09:00
Hmm, too bad. With a Java subclass instead of kotlin, this would be possible – dumazy Oct 17 '17 at 09:02
Yep, that's true. – Adam Arold Oct 17 '17 at 09:05
Does not seem so. How? – Adam Arold Oct 17 '17 at 09:08
