		void f(int i);

		void g(int j);
	}

	class Proxied implements ProxiedInterface {

		public void f(int i) {

		}
	}

	public class Test {
		public static void main(String[] args) throws Exception {
			ProxiedInterface a = (ProxiedInterface) Proxy.newProxyInstance(
					Proxied.class.getClassLoader(),
					new Class[] { ProxiedInterface },
					new handler(new Proxied()));
			a.f(1);

		}
	}

 

请问以上程序的输出是:
