accessing methods of another class

[kourosh parsa]

Hi. Here is the general structure if my code:

public Class Board() extends JPanel{
   // the components of this JPanel are of type Element

   public void save_state(){
   // stuff
   }

   public void add(){
      Class claz = Class.forName("com.x.Banana");
      Element elm = (Element) claz.newInstance();
      this.add(elm);
   }
}
------------
public Class Banana() extends Element{
   Board board;
   public Banana(Board b){
      board = b;
   }

   public void rotate(){
   // stuff
      board.save_state();
   }
}

The problem is that my constructor needs the parameter "Board" which is the handle to the other class, but I cannot pass the parameter in claz.newInstance()
You see that I want to load classes dynamically where the class name is known at run time.
Any ideas what to do about this?

well, I figured out that I can use
Element elm = (Element) claz.getDeclaredConstructor(Board.class).newInstance(this);
instead of
Element elm = (Element) claz.newInstance();

which works fine, but still if anyone has a better proposal, please let share it. Thanks
