问答题

现要求实现一个能够自动生成求职简历的程序，简历的基本内容包括求职者的姓名、性别、年龄及工作经历。希望每份简历中的工作经历有所不同，并尽量减少程序中的重复代码。
现采用原型模式(Prototype)来实现上述要求，得到如图所示的类图。


[Java代码]
Class WorkExperience ______ Cloneable //工作简历
Private String workDate;
Private String company;
Public Object Clone()
______;
obj.workDate=this.workDate;
Obj.company-this.company;
Return obj;


Class Resume ______ Cloneable //简历
Private String name;
Private String sex;
Private String age;
Private WorkExperience work ;
Public Resume(String name)
This.name=name; work=new WorkExperience();

Private Resume(WorkExperience work)
This.woek=______;

Public void SetPersonallnfo( String sex , String age) /*代码略*/
Public void SetWorkExperience(String workDate, String company) /*代码省略*/
Public Object Clone( )
Resume obj=______;
//其余代码省略
Return obj;


Class WorkResume
Public static void main(String[] args)
Resume a=new Resume("张三");
a.SetPersonallnfo("男", "29");
a.SetWorkExperience("1998～2000","XXX公司");
Resume b=______;
b.SetWorkExperience("2001～2006","YYY公司");
