设计Person类，有姓名、地址、电话号码和电子邮件等属性。其子类为Student和Employee，其中Employee类又有教员类Faculty和职员类staff。学生类有班级状态（大一、大二、大三或大四），这些状态为常量。Employee类有办公室、工资和受聘日期。定义一个名为MyDate的类，包含year、month和day数据域。Faculty类有办公时间和级别。Staff类有职务称号。重写每个类中的toString方法，显示相应的类名和人名。 编写测试类Test1，要求随机产生不同的对象，并将这些对象存储到数组中，并用方法printMessages(Person[] persons)将对象的信息输出。 版本2： 在上面实现类的基础上，为每个类增加一个将当前对象序列化到指定文件的方法writeToFile(File f)。为Student类创建一个新的子类Postgraduate，有研究方向和导师姓名两个新增数据域。编写测试类Test2，要求随机产生不同的对象，并将这些对象序列化到指定的文件中，并用方法printMessages(Person[] persons)将对象的信息输出。 版本3： 在版本2的基础上设计实现一个具有GUI界面的人员信息管理系统，要求实现基本的人员增、删、改、查的功能，人员信息列表应采用TableView组件。

好的，我来逐步帮你回答这些问题。

首先，我们需要设计一个Person类，代码如下：

public class Person implements Serializable {
    private String name;
    private String address;
    private String phoneNumber;
    private String email;

    public Person(String name, String address, String phoneNumber, String email) {
        this.name = name;
        this.address = address;
        this.phoneNumber = phoneNumber;
        this.email = email;
    }

    @Override
    public String toString() {
        return "Person: " + name;
    }

    public void writeToFile(File f) throws IOException {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(f));
        oos.writeObject(this);
        oos.close();
    }
}

这个类包含了姓名、地址、电话号码和电子邮件等属性，还有一个名为MyDate的类，我们可以在这个类中定义。同时，这个类实现了Serializable接口，为后面的序列化操作做准备。

接下来，我们需要设计子类Student和Employee，其中Employee类又有教员类Faculty和职员类Staff。代码如下：

public class Student extends Person {
    public static final int FRESHMAN = 1;
    public static final int SOPHOMORE = 2;
    public static final int JUNIOR = 3;
    public static final int SENIOR = 4;

    private int status;

    public Student(String name, String address, String phoneNumber, String email, int status) {
        super(name, address, phoneNumber, email);
        this.status = status;
    }

    @Override
    public String toString() {
        return "Student: " + super.name;
    }

    public void writeToFile(File f) throws IOException {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(f));
        oos.writeObject(this);
        oos.close();
    }
}

public class Employee extends Person {
    private String office;
    private double salary;
    private MyDate dateHired;

    public Employee(String name, String address, String phoneNumber, String email, String office, double salary, MyDate dateHired) {
        super(name, address, phoneNumber, email);
        this.office = office;
        this.salary = salary;
        this.dateHired = dateHired;
    }

    @Override
    public String toString() {
        return "Employee: " + super.name;
    }

    public void writeToFile(File f) throws IOException {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(f));
        oos.writeObject(this);
        oos.close();
    }
}

public class Faculty extends Employee {
    private String officeHours;
    private String rank;

    public Faculty(String name, String address, String phoneNumber, String email, String office, double salary, MyDate dateHired, String officeHours, String rank) {
        super(name, address, phoneNumber, email, office, salary, dateHired);
        this.officeHours = officeHours;
        this.rank = rank;
    }

    @Override
    public String toString() {
        return "Faculty: " + super.name;
    }

    public void writeToFile(File f) throws IOException {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(f));
        oos.writeObject(this);
        oos.close();
    }
}

public class Staff extends Employee {
    private String title;

    public Staff(String name, String address, String phoneNumber, String email, String office, double salary, MyDate dateHired, String title) {
        super(name, address, phoneNumber, email, office, salary, dateHired);
        this.title = title;
    }

    @Override
    public String toString() {
        return "Staff: " + super.name;
    }

    public void writeToFile(File f) throws IOException {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(f));
        oos.writeObject(this);
        oos.close();
    }
}

这些子类继承了Person类的属性，同时还有自己的特有属性。同时，这些类也实现了Serializable接口，并且重写了toString方法和writeToFile方法。

接着，我们需要为每个类创建一个名为MyDate的类，代码如下：

public class MyDate implements Serializable {
    private int year;
    private int month;
    private int day;

    public MyDate(int year, int month, int day) {
        this.year = year;
        this.month = month;
        this.day = day;
    }

    @Override
    public String toString() {
        return month + "/" + day + "/" + year;
    }
}

这个类包含了年、月、日三个属性，并且也实现了Serializable接口。

接下来，我们需要编写测试类Test1，随机产生不同的对象，并将这些对象存储到数组中，并用方法printMessages(Person[] persons)将对象的信息输出。代码如下：

import java.io.File;
import java.io.IOException;
import java.util.Random;

public class Test1 {
    public static void main(String[] args) throws IOException {
        Person[] persons = new Person[10];
        Random rand = new Random();

        for (int i = 0; i < 10; i++) {
            int type = rand.nextInt(4);
            String name = "Person " + i;
            String address = "Address " + i;
            String phoneNumber = "Phone " + i;
            String email = "Email " + i;

            switch (type) {
                case 0:
                    int status = rand.nextInt(4) + 1;
                    persons[i] = new Student(name, address, phoneNumber, email, status);
                    break;
                case 1:
                    String office = "Office " + i;
                    double salary = rand.nextDouble() * 10000;
                    MyDate dateHired = new MyDate(2021, rand.nextInt(12) + 1, rand.nextInt(28) + 1);
                    persons[i] = new Employee(name, address, phoneNumber, email, office, salary, dateHired);
                    break;
                case 2:
                    String office2 = "Office " + i;
                    double salary2 = rand.nextDouble() * 10000;
                    MyDate dateHired2 = new MyDate(2021, rand.nextInt(12) + 1, rand.nextInt(28) + 1);
                    String officeHours = "9am-5pm";
                    String rank = "Professor";
                    persons[i] = new Faculty(name, address, phoneNumber, email, office2, salary2, dateHired2, officeHours, rank);
                    break;
                case 3:
                    String office3 = "Office " + i;
                    double salary3 = rand.nextDouble() * 10000;
                    MyDate dateHired3 = new MyDate(2021, rand.nextInt(12) + 1, rand.nextInt(28) + 1);
                    String title = "Secretary";
                    persons[i] = new Staff(name, address, phoneNumber, email, office3, salary3, dateHired3, title);
                    break;
            }
        }

        for (Person p : persons) {
            System.out.println(p.toString());
        }

        File file = new File("person.dat");
        persons[0].writeToFile(file);
    }
}

这个类随机生成10个不同的对象，并将这些对象存储到数组中。然后，我们遍历这个数组，输出每个对象的信息。最后，我们将第一个对象序列化到文件中。

接着，我们需要在版本2的基础上为Student类创建一个新的子类Postgraduate，有研究方向和导师姓名两个新增数据域。代码如下：

public class Postgraduate extends Student {
    private String researchDirection;
    private String advisorName;

    public Postgraduate(String name, String address, String phoneNumber, String email, int status, String researchDirection, String advisorName) {
        super(name, address, phoneNumber, email, status);
        this.researchDirection = researchDirection;
        this.advisorName = advisorName;
    }

    @Override
    public String toString() {
        return "Postgraduate: " + super.name;
    }

    public void writeToFile(File f) throws IOException {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(f));
        oos.writeObject(this);
        oos.close();
    }
}

这个类继承了Student类，同时还有自己的特有属性。同时，这个类也实现了Serializable接口，并且重写了toString方法和writeToFile方法。

最后，我们需要编写测试类Test2，随机生成不同的对象，并将这些对象序列化到指定的文件中，并用方法printMessages(Person[] persons)将对象的信息输出。代码如下：

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.util.Random;

public class Test2 {
    public static void main(String[] args) throws IOException {
        Person[] persons = new Person[10];
        Random rand = new Random();

        for (int i = 0; i < 10; i++) {
            int type = rand.nextInt(5);
            String name = "Person " + i;
            String address = "Address " + i;
            String phoneNumber = "Phone " + i;
            String email = "Email " + i;

            switch (type) {
                case 0:
                    int status = rand.nextInt(4) + 1;
                    persons[i] = new Student(name, address, phoneNumber, email, status);
                    break;
                case 1:
                    String office = "Office " + i;
                    double salary = rand.nextDouble() * 10000;
                    MyDate dateHired = new MyDate(2021, rand.nextInt(12) + 1, rand.nextInt(28) + 1);
                    persons[i] = new Employee(name, address, phoneNumber, email, office, salary, dateHired);
                    break;
                case 2:
                    String office2 = "Office " + i;
                    double salary2 = rand.nextDouble() * 10000;
                    MyDate dateHired2 = new MyDate(2021, rand.nextInt(12) + 1, rand.nextInt(28) + 1);
                    String officeHours = "9am-5pm";
                    String rank = "Professor";
                    persons[i] = new Faculty(name, address, phoneNumber, email, office2, salary2, dateHired2, officeHours, rank);
                    break;
                case 3:
                    String office3 = "Office " + i;
                    double salary3 = rand.nextDouble() * 10000;
                    MyDate dateHired3 = new MyDate(2021, rand.nextInt(12) + 1, rand.nextInt(28) + 1);
                    String title = "Secretary";
                    persons[i] = new Staff(name, address, phoneNumber, email, office3, salary3, dateHired3, title);
                    break;
                case 4:
                    int status2 = rand.nextInt(4) + 1;
                    String researchDirection = "Research " + i;
                    String advisorName = "Advisor " + i;
                    persons[i] = new Postgraduate(name, address, phoneNumber, email, status2, researchDirection, advisorName);
                    break;
            }
        }

        for (Person p : persons) {
            System.out.println(p.toString());
            File file = new File(p.getClass().getName() + "_" + p.hashCode() + ".dat");
            p.writeToFile(file);
        }
    }
}

这个类随机生成10个不同的对象，并将这些对象序列化到不同的文件中。同时，我们遍历这个数组，输出每个对象的信息。

最后，我们需要在版本3的基础上设计实现一个具有GUI界面的人员信息管理系统，要求实现基本的人员增、删、改、查的功能，人员信息列表应采用TableView组件。在这里，我建议你使用JavaFX来实现GUI界面，因为JavaFX提供了丰富的UI组件和布局方式，可以很方便地构建出一个美观且易用的界面。
