实验五1. 定义一个商品类，在此基础上定义一个食品子类，一个服装子类。假设任何商品都应该有商品编号、商品名称、出厂日期、产品厂家名称等信息，除此之外，食品应该有保质期、主要成分等信息，服装应该有型号、面料等信息。/file name:ProductClass.javaimport java util.*;public class ProductClass private int No; private String name; private int date; private String company; public ProductClass() public ProductClass(int No,String name,int date,String company) this.No=No; =new String(name); this.date=date; pany=new String(company);public void setNo(int No)this.No=No;public void setname(String name)=new String(name);public void setdate(int date)this.date=date;public void setcompany(String company)pany=new String(company);public int getNo()return No;public String getname()return name;public int getdate()return date;public String getcompany()return company;public String toString() returnnNo:+No+nname:+name+ndate:+date+ncompany:+company;/file name:FoodClass.javapublic class FoodClass extends ProductClass private int time; private String fen; public FoodClass()super();public FoodClass(int No,String name,int date,String company,int time,String fen) super(No,name,date,company); this.time=time; this.fen=new String(fen);public void settime(int time)this.time=time;public void setfen(String fen)this.fen=new String(fen);public int gettime()return time;public String getfen()return fen;public String toString() return super.toString()+ntime:+time+nfen:+fen; /file name:ClothseClass.javapublic class ClothseClass extends ProductClass public int type; public String material; public ClothseClass() super();public ClothseClass( int No,String name,int date,String company,int type,String material) super(No,name,date,company); this.type=type; this.material=new String(material);public void settype(int type)this.type=type;public void setmaterial(String material)this.material=new String(material);public int gettype()return type;public String getmaterial()return material;public String toString() return super.toString()+ntype:+type+nmaterial:+material; /file name: TextProductClass.javapublic class TextProductClass public static void main(Stringagrs) ProductClass info=new ProductClass3; info0=new ProductClass(1,ww,1991,shanghai); info1=new FoodClass(2,zz,1950,beijng,12,mian); info2=new ClothseClass(3,ll,1920,nanjing,47,dilun); for( int i=0;i3;i+) System.out.println(infoi); 运行结果：3、为教师工作证与学生证设计一个类层次结构，尽可能地保证代码的重用率。假设工作证包括编号、姓名、性别、出生年月、职务和签发工作证日期；学生证包括编号、姓名、性别、出生年月、系别、入校日期及每学年的注册信息。/file name:CardClass.javaimport java.util.*;public class CardClass private int No; private String name; private boolean sex; private int birthday; public CardClass() public CardClass(int No, String name, boolean sex, int birthday) this.No = No; = new String(name); this.sex = sex; this.birthday = birthday; public void setNo(int No)this.No = No; public void setName(String name) = new String(name); public void setSex(boolean sex)this.sex = sex;public void setBirthday(int birthday) this.birthday = birthday;public int getNo() return No; public String getName()return name; public boolean getSex()return sex; public int getBirthday()return birthday;public String toString() return nNo: + No + nName: + name + nSex: + sex +nBrithday: + birthday; /file name:TeachercardClass.javapublic class TeachercardClass extends CardClass private String duty;private int registration; public TeachercardClass() super();public TeachercardClass(int No, String name, boolean sex, int birthday, String duty,int registration) super(No, name, sex, birthday); this.duty = new String(duty); this.registration = registration; public void setDuty(String duty) this.duty = new String(duty); public void setRegistration(int registration) this.registration = registration; public String getDuty() return duty; public double getRegistration() return registration;public String toString() return super.toString() + nDuty: + duty + nRegistration: + registration; /file name:StudentcradClass.javapublic class StudentcardClass extends CardClass private String major; private int addmision;private String registration;public StudentcardClass() super();public StudentcardClass(int No, String name, boolean sex,int birthday, String major,int addmision,String registration) super(No, name, sex, birthday); this.major = new String(major); this.addmision = addmision; this.registration=new String(registration) ; public void setMajor(String major) this.major = new String(major); public void setAddmision (int addmision) this.addmision = addmision;public void setRegistration(String registration) this.registration=new String(registration) ;public String getMajor() return major;public int getAddmision() return addmision;public String getregistration() return registration; public String toString() return super.toString() + nMajor: + major + nAddmision: +addmision+nRegistration:+ registration; /file name:TextcardClass.javapublic class TestCardClass public static void main(String agrs)CardClass info = new Ca
