2.model（职工类，读数据，写数据）
（1）职工类：

package model;import Controller.BirthdayErrorException;
import Controller.EmailErrorException;
import Controller.NameException;
import Controller.NumFromatException;import java.io.Serializable;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;public class Employee implements Serializable {private String No;   //员工工号private String Name; //员工姓名private String BirthDay;//员工出生日期private String Sal;     //员工工资private String Email;  //员工邮箱static int i=0; //员工入职的序号public Employee() {}public Employee(String name, String birthDay,String sal, String email) throws EmailErrorException, BirthdayErrorException, NumFromatException, NameException {if(name.isEmpty())  //检查名字是否为空{throw new NameException();}if(!check_email(email))  //检查邮箱格式{throw new EmailErrorException();}if(!check_birthday(birthDay))//检查出生日期格式{throw new BirthdayErrorException();}if(!check_sal(sal))//检查工资格式{throw new NumFromatException();}No=CreateNo();Name = name;BirthDay = birthDay;Sal = sal;Email=email;}public static boolean check_sal(String sal) {  //检查工资格式String format = "^[0-9]*$";return sal.matches(format);}public static boolean check_birthday(String birthDay) {//检查出生日期格式String format="^\\d{4}-\\d{1,2}-\\d{1,2}";return birthDay.matches(format);}public static boolean check_email(String email) {//检查邮箱格式String format = "[a-zA-Z0-9_]{1,}[@][a-z0-9]{2,3}[.][a-z]{2,3}";return email.matches(format);}private String CreateNo()   //根据日期，入职顺序创建工号{   ArrayList<Employee> arrayList = ReadData.Read();//读取数据文件if(arrayList!=null && arrayList.size()!=0)  /*如果此时数据文件里存在内容，为了确保员工编号不会重复，从数据文件中读取最后一个员工的工号的后两位*/{String temp_no = arrayList.get(arrayList.size()-1).getNo();i = Integer.parseInt(temp_no.substring(temp_no.length()-2,temp_no.length()));}Date date = new Date();//生成当前日期i++;    //  计算员工编号最后两位SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyyMM");String o=null;if(i<10)  //为了确保工号格式，做一下判断如果是个位数，在个位数前加0{o="0"+ Employee.i;}else o=Employee.i+"";String no = simpleDateFormat.format(date)+o;return no;}public String getNo() {return No;}public void setNo(String no) {No = no;}public String getName() {return Name;}public void setName(String name) {Name = name;}public String getBirthDay() {return BirthDay;}public void setBirthDay(String birthDay) {BirthDay = birthDay;}public String getSal() {return Sal;}public void setSal(String sal) {Sal = sal;}public String getEmail() {return Email;}public void setEmail(String email) {Email = email;}@Overridepublic String toString() {return "Employee{" +"No='" + No + '\'' +", Name='" + Name + '\'' +", BirthDay='" + BirthDay + '\'' +", Email='" + Email + '\'' +'}';}
}
//        if(arrayList!=null && arrayList.size()!=0)
//        {
//            for(Employee e : arrayList)
//            {
//                if(o.equals(e.getNo().substring(6,7)))
//                {
//                    i++;
//                    if(i<10)
//                    {
//                        o="0"+ Employee.i;
//                    }
//                    else o=Employee.i+"";
//                    break;
//                }
//            }
//        }

（2）读取数据：

package model;import java.io.FileInputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.util.ArrayList;public class ReadData {public static ArrayList<Employee> Read()   //文件反序列化{try {ObjectInputStream objectInputStream = new ObjectInputStream(new FileInputStream("Emps"));Object obj = objectInputStream.readObject();if(obj instanceof ArrayList){ArrayList<Employee> obj1 = (ArrayList<Employee>) obj;return obj1;}} catch (ClassNotFoundException | IOException e) {// e.printStackTrace();}return null;}}

（3）写入数据

package model;import java.io.*;
import java.util.ArrayList;
import java.util.Stack;public class Save  {public static ArrayList<Employee>Emps = new ArrayList<>();public Save() {}public Save(Employee e) {refresh(e);}public static void refresh(Employee Emp){   //当文件为空或不存在时，使用该种方式添加Emps.add(Emp);Serializable();}public static void delete_refresh(ArrayList<Employee>Emp)  //当文件存在时，使用这种方式添加{Emps=Emp;Serializable();}public static void Serializable()  //文件序列化过程{try {ObjectOutputStream objectOutputStream = new ObjectOutputStream(new FileOutputStream("Emps"));objectOutputStream.writeObject(Emps);objectOutputStream.flush();objectOutputStream.close();} catch (IOException e) {e.printStackTrace();}}}

3.处理数据（各类功能）

（1）求平均值：

package Controller;import model.Employee;
import model.ReadData;
import model.Save;import java.util.ArrayList;public class AvgSal {public static double avgsal() throws EmptyException {double sum=0;ArrayList<Employee> arrayList = ReadData.Read();   //读取数据文件，反序列化if(arrayList==null || arrayList.size()==0)  //如果数据文件为空或不存在抛出异常{throw new EmptyException();}for(Employee e: arrayList)   //计算平均值{sum+=Double.parseDouble(e.getSal());}return sum/arrayList.size();}
}

（2）记录员工人数：

package Controller;import model.Employee;
import model.ReadData;
import model.Save;import java.util.ArrayList;public class Count {public static int count() throws EmptyException {ArrayList<Employee> arrayList = ReadData.Read(); //获取数据文件，反序列化if(arrayList==null || arrayList.size()==0){throw new EmptyException();}return arrayList.size();  //返回arraylist的大小（人数）}}

（3）删除员工

package Controller;
import model.Employee;
import model.ReadData;
import model.Save;
import java.util.ArrayList;
public class Delete {public static void delete(String No) throws EmptyException, NotFoundNoException {ArrayList<Employee> arrayList = ReadData.Read();  //读取数据文件，反序列化if(arrayList==null || arrayList.size()==0){throw new EmptyException();}int flag=0;//flag的作用是，当删除的员工编号不存在时，及时抛出异常，for (Employee e : arrayList) {          //通过遍历数据文件，找到需要删除的员工的编号，进行删除if (e.getNo().equals(No)) {flag=1;arrayList.remove(e);Save.delete_refresh(arrayList);//删除数据后，及时修改本地文件return;}}if(flag==0){throw new NotFoundNoException();}}
}

（4）得到最高工资的员工信息：

package Controller;import model.Employee;
import model.ReadData;
import model.Save;import java.util.ArrayList;public class HighestSal {public  static  Employee high() throws EmptyException {double max=-1;ArrayList<Employee> arrayList = ReadData.Read(); //读取数据文件，反序列化if(arrayList==null || arrayList.size()==0){throw new EmptyException();}Employee re=null;for(Employee e: arrayList)   //遍历数据找出最高工资的员工{if(max<Double.parseDouble(e.getSal())){max = Double.parseDouble(e.getSal());re=e;}}return re;    //返回该员工的信息}}

（5）得到最低工资的员工信息

package Controller;import model.Employee;
import model.ReadData;
import model.Save;import java.util.ArrayList;public class LowestSal {public  static  Employee low() throws EmptyException {double min=Double.MAX_VALUE;ArrayList<Employee> arrayList = ReadData.Read();//读取数据文件，反序列化if(arrayList==null || arrayList.size()==0){throw new EmptyException();}Employee re=null;for(Employee e: arrayList)//遍历数据找出最低工资的员工{if(min>Double.parseDouble(e.getSal())){min = Double.parseDouble(e.getSal());re=e;}}return  re;  //返回员工信息}
}

（6）全体员工信息：

package Controller;import model.Employee;
import model.ReadData;
import model.Save;import java.util.ArrayList;public class ShowInfo {public static ArrayList<Employee> showinfo() throws EmptyException {ArrayList<Employee> arrayList = ReadData.Read();//读取数据文件，反序列化if(arrayList==null || arrayList.size()==0){throw new EmptyException();}return arrayList;  //将数据返回与图形化界面交互}
}

（7）更新员工信息：

package Controller;import model.Employee;
import model.ReadData;
import model.Save;import java.util.ArrayList;import static model.Employee.*;public class Update {public Update() {}//更新员工信息public static void update(String name,String birthday,String sal,String email,String No) throws NotFoundNoException, EmptyException, EmailErrorException, BirthdayErrorException, NumFromatException {int flag=0; //flag的作用还是用来标记输入的员工ArrayList<Employee> arrayList = ReadData.Read(); //读取数据文件，反序列化if(arrayList==null || arrayList.size()==0)  //数据为空或不存在时抛出异常{throw new EmptyException();}if(!email.isEmpty()&&!check_email(email))    //如果用户输入的邮箱不合法，则抛出异常{throw new EmailErrorException();}if(!birthday.isEmpty()&&!check_birthday(birthday))  //用户输入生日日期格式错误抛出异常{throw new BirthdayErrorException();}if(!sal.isEmpty()&&!check_sal(sal))   //如果用户输入的工资不是数字的话抛出异常{throw new NumFromatException();}Employee old_e = null;for(Employee e:arrayList)   //遍历数据{if(e.getNo().equals(No)){old_e=e; //记录旧的数据方便对数据进行更新if(!name.isEmpty())  //当名字非空时，修改名字，下免得if语句的功能都是这样，保证用户可以对单一的数据进行// 修改{e.setName(name);}else if(!birthday.isEmpty()){e.setBirthDay(birthday);}else if(!sal.isEmpty()){e.setBirthDay(birthday);}arrayList.remove(old_e); //移除旧的数据arrayList.add(e); //添加修改后的数据Save.delete_refresh(arrayList);//对于本地文件进行更新操作return;}}if(flag==0){throw new NotFoundNoException();}}
}

（8）添加新员工：

package Controller;import model.Employee;
import model.ReadData;
import model.Save;import java.util.ArrayList;public class Write {Employee employee;public Write() {}public Write(Employee emp) throws EmpNullException {if(emp==null)    //如果用户输入的用户信息为空。抛出异常{throw new EmpNullException();}ArrayList<Employee> arrayList = ReadData.Read(); //读取数据if(arrayList==null || arrayList.size()==0)  /*如果添加的时候还没有员工数据，这时候直接通过save来添加，无需更新数据*/{new Save(emp);}else{arrayList.add(emp);      //添加新数据Save.delete_refresh(arrayList);//将旧的数据更新覆盖}}
}

以下是各类异常：

package Controller;public class BirthdayErrorException extends Exception{public BirthdayErrorException (){}public BirthdayErrorException (String s){super(s);}
}
package Controller;public class EmailErrorException extends Exception{public EmailErrorException(){}public EmailErrorException(String s){super(s);}}
package Controller;public class EmpNullException extends Exception{public EmpNullException (){}public EmpNullException(String s){super(s);}
}
package Controller;public class EmptyException extends Exception {
public EmptyException(){}
public EmptyException(String s){super(s);}
}
package Controller;public class NameException extends Exception{public NameException (){}public NameException(String s){super(s);}
}
package Controller;public class NotFoundNoException extends Exception {public NotFoundNoException(){}public NotFoundNoException(String s){super(s);}}package Controller;public class NumFromatException extends Exception{public NumFromatException(){}public NumFromatException(String s){super(s);}
}
