Answer 1

Use reflection:

public static List getSuperClasses(Object o) {
  List classList = new ArrayList();
  Class class= o.getClass();
  Class superclass = class.getSuperclass();
  classList.add(superclass);
  while (superclass != null) {   
    class = superclass;
    superclass = class.getSuperclass();
    classList.add(superclass);
  }
  return classList;
}
