@JvmStatic methods

Similarly to properties, we can apply @JvmStatic to methods defined on companion objects or named objects. Let's examine this by adding a method to our existing companion object:

class Widget {    companion object {        ...        fun goo() { }    }}

From Java, we can then use this method by once again using an instance of the companion object:

// Main.javapublic class Main {    public static void main(String[] args) {        Widget.Companion.goo();    }}

In this example, we must reference the companion object instance because the goo() method is a member of the companion object itself, as seen in the following generated code:

public final class Widget {   ...   public static final class Companion {      ...      public final void goo() {      }      ...   }}
