See below, how can I call animals growl while within a method of my
interface (I need that - cant get rid of it).

public class animal {
  public void growl() {
     System.out.println("growl");
  }
}

public class dog extends animal {

  public void growl() {
     IDefaultCall default = new IDefaultCall () {

       public void execute() {
          // I can do it this as super. points to IDefaultCell !
          super.growl();
       }
      };
     call (default);
  }

}
