也玩java反射

try {
        	//利用反射拿到我们要的class类
			Class clazz = Class.forName("com.luch.sample.common.thread.Jack");
			//拿到类的属性名
			Field field = clazz.getField("name");
			//获取属性的值
			String obj = (String) field.get(clazz.newInstance());
			System.out.println(obj);
			

			Field[] fields = clazz.getDeclaredFields();
			for(Field fld: fields) {
				obj = (String) fld.get(clazz.newInstance());
				System.out.println(obj);
			}
			//拿到类的方法,null是方法的参数
			Method method = clazz.getMethod("test", null);
			method.invoke(clazz.newInstance(), null);
			//拿到类的方法,null是方法的参数
		    method = clazz.getMethod("fetchAge", new Class[]{String.class});
			method.invoke(clazz.newInstance(), new Object[]{new String("1987-07-15")});
			
        } catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
