if I have a top-level

fun

how can I make a static import for it in Java?

I just tried it, it sorta just works

if for example your function is called "foo" in a "Bar.kt" file you'll need to import BarKt.foo

Right, you will need to import the

Kt

-suffixed class

I've been trying

import static package.BarKt.foo

and I can't get it to work, I can call the fun using

BarKt.foo()

but I can't figure out how to reduce that to just

foo()

with a static import

No, it definitely is possible, I literally just wrote a working example

ah ok maybe i'm doing something wrong

Well, it’s not static in the traditional JVM sense, but that shouldn’t matter in this case

do I have to make an object?

nope

ah hah ok i figured it out

What was wrong?

ok, no I need to work on it some more.. something is strange here.. when I click the method with the error it goes to the java api

toString()

method but mine is actually

toString(Exception)

sounds kinda like you have some kind of collision or shadowing issue

but shouldn't happen with different signatures, right?

I mean, it shouldn’t, but you also shouldn’t have this much issue with the static import

on your sample code, if you click alt-enter on your

BarKt

of the `BarKt.foo()`call, do you get the option to import it? I get no options

if I start with

import package.BarKt

and invoke

BarKt.foo()

, I do get an intention on the

BarKt

segment for an on-demand static import for

BarKt

ok, you were right.. if I change the name to

toZString()

it works

It might be an IntelliJ optimizing imports issue?

I think it’s a Java limitation - class member methods with the same name as statically-imported ones will always trump the latter, even if the signatures differ. You can reproduce with a Kotlin file like this:

// Foo.kt
package foobar

fun frobnicate(widget: Int) = Unit

And a Java file containing this:

// Bar.java
package foobar;

import static foobar.FooKt.frobnicate;

public class Bar {
  public void frobnicate() {  }
  public static void qux() {
    frobnicate(42);  // Non-static method 'frobnicate' cannot be referenced from a static context
  }
}
