设计一个名为Person的类及其两个名为学生Student和雇员Employee的子类。employee类又有子类：教员类Faculty和职员类Staff。 （1）每个人都有姓名、地址、电话和电子邮件 （2）学生有班级状态（大一、大二、大三、大四） （3）雇员涉及办公室、工资、受聘日期 （4）教员有办公时间和级别。 （5）职员有头衔 写一个测试程序，创建Person、Student、Employee、faculty、Staff，并且调用他们的toString方法。

下面是一个符合要求的Java代码实现：

public class Person {
    private String name;
    private String address;
    private String phone;
    private String email;

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

    public String getName() {
        return name;
    }

    public String getAddress() {
        return address;
    }

    public String getPhone() {
        return phone;
    }

    public String getEmail() {
        return email;
    }

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

public class Student extends Person {
    private String status;

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

    public String getStatus() {
        return status;
    }

    public String toString() {
        return "Student: " + getName();
    }
}

public class Employee extends Person {
    private String office;
    private double salary;
    private Date hireDate;

    public Employee(String name, String address, String phone, String email, String office, double salary, Date hireDate) {
        super(name, address, phone, email);
        this.office = office;
        this.salary = salary;
        this.hireDate = hireDate;
    }

    public String getOffice() {
        return office;
    }

    public double getSalary() {
        return salary;
    }

    public Date getHireDate() {
        return hireDate;
    }

    public String toString() {
        return "Employee: " + getName();
    }
}

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

    public Faculty(String name, String address, String phone, String email, String office, double salary, Date hireDate, String officeHours, String rank) {
        super(name, address, phone, email, office, salary, hireDate);
        this.officeHours = officeHours;
        this.rank = rank;
    }

    public String getOfficeHours() {
        return officeHours;
    }

    public String getRank() {
        return rank;
    }

    public String toString() {
        return "Faculty: " + getName();
    }
}

public class Staff extends Employee {
    private String title;

    public Staff(String name, String address, String phone, String email, String office, double salary, Date hireDate, String title) {
        super(name, address, phone, email, office, salary, hireDate);
        this.title = title;
    }

    public String getTitle() {
        return title;
    }

    public String toString() {
        return "Staff: " + getName();
    }
}

public class TestPerson {
    public static void main(String[] args) {
        Person p = new Person("张三", "北京市海淀区", "123456789", "zhangsan@abc.com");
        Student s = new Student("李四", "北京市朝阳区", "987654321", "lisi@abc.com", "大二");
        Employee e = new Employee("王五", "北京市丰台区", "567891234", "wangwu@abc.com", "A101", 10000.0, new Date());
        Faculty f = new Faculty("赵六", "北京市东城区", "456789123", "zhaoliu@abc.com", "B102", 15000.0, new Date(), "周一至周五 8:00-17:00", "教授");
        Staff st = new Staff("钱七", "北京市西城区", "789123456", "qianqi@abc.com", "C103", 8000.0, new Date(), "职员");

        System.out.println(p.toString());
        System.out.println(s.toString());
        System.out.println(e.toString());
        System.out.println(f.toString());
        System.out.println(st.toString());
    }
}

在测试程序中，通过创建不同的对象，分别调用它们的toString方法输出对应的结果。
