Java 反射 调用运行时类对象等等

 @Test
    public void test2() throws Exception, InstantiationException {
        //获取当前Class
        /**
         * //获取 Class 的几种方式
         *         Class<Person> clazz1 = Person.class;
         *         System.out.println(clazz1);
         *
         *         Person p1 = new Person();
         *         Class clazz2 = p1.getClass();
         *         Class clazz3 = Class.forName("com.study.refilex.Person");
         */
        Class clazz = Person.class;
        //创建当前运行时类对象
        Person person = (Person)clazz.newInstance();
        //获取当前运行时类的属性
        Field name = clazz.getDeclaredField("name");
        //保证当前属性是可以访问的
        name.setAccessible(true);
        //设置当前运行时类对象的属性的值
        name.set(person,"xingming");
        //获取此对象的值
        System.out.println(name.get(person));
    }
