How to call parent static method using child class in kotlin?

I have a java class AAA with a static method:

public class AAA {
    public static void foo() {}
}

and a kotlin class which extends it:

class BBB : AAA() {}

Now in other kotlin file I would like to call that method. If I do it like this then it works:

fun bar() {
    AAA.foo()
}

but when I'm doing it like this it doesn't compile (Unresolved reference: foo):

fun bar() {
    BBB.foo()
}

Is it possible to call parent static method using child class BBB in kotlin? In java there is no problem with that.

Solution

No, according to Calling Java from Kotlin, this is how Java's static members are ported to Kotlin:

Static members of Java classes form "companion objects" for these classes. You can't pass such a "companion object" around as a value but can access the members explicitly.

You don't inherit the companion object of a superclass in Kotlin.

open class A {
    companion object {
        fun foo() {}
    }
}

class B: A() {
    fun bar() {
        // this doesn't work because B.Companion does not exist
        B.foo()

        // these work, because these are implicitly A.Companion.foo()
        foo()
        A.foo()
    }
}

Technically, you could write a companion object in BBB that has all the static members of AAA:

class BBB : AAA() {
    companion object {
        // this allows you to do BBB.foo()
        val foo = AAA::foo
    }
}

Though I think that's beside the point.

That said, this doesn't really matter at the end of the day. Practically, you don't lose anything by doing AAA.foo().
