How to addObject in constructor of an actor class

I was wondering if it was possible to add an object to the world if the Building constructor has been called into a world. I would like to know if you can get the X and Y value of the Building in the world if it was called. 
    private StatBar healthBar = new StatBar(100, currentHp, null, 100, 10,0, Color.GREEN, Color.RED, false, Color.WHITE, 1);
    
    public Building(){        
        World world = getWorld();
        image = drawBuilding();
        setImage (image);
        world.addObject(healthBar, (Building.class).getX(), getY() - 50);
        
    }

The problem is that when the object is created it is not in a world yet. So, it has to add itself to the world first, then it can add other objects. These information have to be passed into the constructor. 
public Building(World world, int x, int y) {
    world.addObject(this, x, y);
    world.addObject(healthBar, x, y - 50);
    // Some other stuff
}
By doing so you can also replace this 
Building building = new Building();
addObject(building, someX, someY);
with this 
new Building(this, someX, someY);
