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
[解决办法]
Label.java

@Target({ ElementType.TYPE, ElementType.FIELD })
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Label {
    String chineseLabel();
}

Person.java

    @Label(chineseLabel = "年龄")
    Integer age;

    @Label(chineseLabel = "身份证号")
    String idNo;

    @Label(chineseLabel = "是否已婚(已婚：T,未婚：F)")
    Boolean isMerried;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSex() {
        return sex;

    public void setSex(String sex) {
        this.sex = sex;
