我可以在 java 中使用什么来代替 Kotlin 中的 run 函数？

Question

I try to convert code Kotlin to java and I could not find run function in java. This is Kotlin code :

private val resumeArElementsTask = Runnable {
    locationScene?.resume()
    arSceneView!!.resume()
}

And I use resumeArElementsTask like

resumeArElementsTask.run {
            computeNewScaleModifierBasedOnDistance(locationMarker, locationNode.distance)
        }

When I convert to java

private final Runnable resumeArElementsTask = new Runnable() {

    @Override
    public void run() {
        locationScene.resume();
        try {
            arSceneView.resume();
        } catch (CameraNotAvailableException e) {
            e.printStackTrace();
        }

    }
};

How can I use run function in java and convert this code to java

 resumeArElementsTask.run {
            computeNewScaleModifierBasedOnDistance(locationMarker, locationNode.distance)
        }

Thanks

The following Java code is exactly equivalent to what your Kotlin code actually does:

computeNewScaleModifierBasedOnDistance(locationMarker, locationNode.getDistance());

Note that it doesn't resume anything. Your Kotlin code doesn't, either. It looks like it does, but it doesn't.

It sounds like you just want to write

runnable.run();
computeNewScaleModifierBasedOnDistance(locationMarker, locationNode.getDistance());
