How to call a method in Java?

IDE

I would like to call this public method in my extension using Java code. I want it to be a purple method block, but I don’t know how to.

Can somebody teach me?

First create object of this class and then name it like abs
Now to call method do like this

You tell me

I think it is WallpaperManager.

Ok then do like this

WallpaperManager objectName = new WallpaperManager('pass parameters if required');

objectName.clearWallpaper();

I used this.

    @SimpleFunction(description = "Reset all wallpaper to the factory default.")
    public void ClearWallpaper(){
      WallpaperManager objectName = new WallpaperManager();
      objectName.clearWallpaper();
    }
}

It returned an error when compiling.
