Using a for loop in an arraylist
 
Hello, I'm having some beginner dificulties with programming an arraylist to draw certain objects from subclasses.
In my paint method I want to use a for loop to walk through my arraylist and draw these objects, like this:

Code:

//een arraylist die wordt gevuld met de bewegendedelen
        ArrayList<BewegendeDelen> bewegendedelenarray = new ArrayList<BewegendeDelen>();
       
        //voeg de ruimteschip en alien objecten toe aan de arraylist
        bewegendedelenarray.add(new Ruimteschip());
        bewegendedelenarray.add(new Alien());
       
       
       
        //tekenen
        public void paint(Graphics G)
        {
                for(BewegendeDelen obj : bewegendedelenarray)
                {        //teken de bewegende delen (ruimteschip, aliens)
                       
                }       
        }

How will I get this working?!
thanks in advance!
