哪位有时间，帮忙写下这个的实现过程，让我参考学习一下（非作业）
创建Person类，Person的属性有：
Strng name 姓名
String sex 性别
Integer age 年龄,
String idNo 身份证号
Boolean isMerried 是否已婚
请生成相应的getter、setter方法。请编写注解@Label，表示所注解对象的中文名称，请把@Label注解标注在Person类和Person的每个属性上面。请编写PersonInput类，负责提示录入人员的相关属性，提示必须是注解@Label所标注的中文名称。请编写PersonDisplay，负责显示人员信息，显示时的属性名称必须为注解@Label所标注的中文名称，PersonInput类与PersonDisplay类实现了共同的接口PersonAction，接口PersonAction有方法process，方法process的签名为：public Person process(Person person);
PersonDisplay和PersonInput具体怎么实现的？ annotation interface
