Java之反射举例

package reflection;

import bean.User;

public class ReflectionDemo {
    public static void main(String[] args) throws Exception {
        //获取类名，含包名
        System.out.println(User.class.getName());

        //通过类名反射实例化对象
        User user = (User) Class.forName(User.class.getName()).newInstance();
        System.out.println(user);


    }

运行结果：

bean.User
User[name='null', age=null, address='null']
