  Car car = Car();
  InvocationHandler h = new jdkProxy(car);
  Class<?> cls = car.getClass();
  IMoveable proxycar = (IMoveable) Proxy.(cls.getClassLoader()cls.getInterfaces()h);
   proxycar.move()Class<?> cls2 = proxycar.getClass();
   IMoveable proxycar2 = (IMoveable) Proxy.(cls2.getClassLoader(),cls2.getInterfaces(),new jdkProxy2(proxycar));
    proxycar2.move();
