获取构造器

    public void test6() throws ClassNotFoundException{        //方法一：通过运行时类来获取Class        Class c=Persion.class;        Constructor[] constructor=c.getDeclaredConstructors();        for (Constructor cc:constructor) {            System.out.println(cc);        }        //方法二：通过Class的静态方法来获取Class                String className="com.tt.Persion";                Class c1=Class.forName(className);                Constructor[] constructor1=c1.getDeclaredConstructors();                for (Constructor cc:constructor1) {                    System.out.println(cc);                }    }
