How can I call a method of an object that is stored in an ArrayList?

Question

Hello,
I am working on a simple game.
I have my own collection class that can contain some Brick objects.
That class looks like this:
class MyCollection<Brick>
      ArrayList<Brick> list = new ArrayList<Brick>();
      public void add(Brick obj)
            list.add(obj);
     public int get(int i)
            return list.get(i);
     public int length()
           return list.size();
}My Brick class is abstract and contains this method:
public abstract int getXpos();That method is overridden by the subclass Brick_type1 (which, of course, extends Brick) and returns an int.
In my main class I try to call the getXpos() method but I cannot call if for an unknown reason:
MyCollection mc = new MyCollection<Brick>();
Brick_type1 bt = new Brick_type1(10);
mc.add(bt);
for(int i = 0; i<mc.length(); i++)
            System.out.println(bc.get(i).getXpos());   // getXpos() does not exist, says the compilatorbc.get(i) should return a Brick that contains the getXpos() method, so why can´t I call it?

Sorry, it should be:
public Brick get(int i)
return list.get(i);
}...so it actually returns a Brick, but I still cannot call the getXpos() method for some reason.Is this also just a typo?
MyCollection mc = new MyCollection<Brick>();
