Design a class named Person and its two subclasses named Student and Employee.  Make Faculty and Staff subclasses of Employee. A person has a name,  address, phone_number, and e-mail address. A student has a status (freshman, sophomore, junior, or senior).  An employee  has an office, salary. A faculty member has office_hours and a rank. A staff member has a title. Override the toString() method in each of these classes to display their details. Write a Java application and subsequent pseudocode to implement/simulate the same.

Here is the Java code for the classes:

public class Person {
    String name;
    String address;
    String phoneNumber;
    String email;

    @Override
    public String toString() {
        return "Person [name=" + name + ", address=" + address + ", phoneNumber=" + phoneNumber + ", email=" + email + "]";
    }
}

public class Student extends Person {
    String status;

    @Override
    public String toString() {
        return "Student [status=" + status + ", name=" + name + ", address=" + address + ", phoneNumber=" + phoneNumber + ", email=" + email + "]";
    }
}

public class Employee extends Person {
    String office;
    double salary;

    @Override
    public String toString() {
        return "Employee [office=" + office + ", salary=" + salary + ", name=" + name + ", address=" + address + ", phoneNumber=" + phoneNumber + ", email=" + email + "]";
    }
}

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

    @Override
    public String toString() {
        return "Faculty [officeHours=" + officeHours + ", rank=" + rank + ", office=" + office + ", salary=" + salary + ", name=" + name + ", address=" + address + ", phoneNumber=" + phoneNumber + ", email=" + email + "]";
    }
}

public class Staff extends Employee {
    String title;

    @Override
    public String toString() {
        return "Staff [title=" + title + ", office=" + office + ", salary=" + salary + ", name=" + name + ", address=" + address + ", phoneNumber=" + phoneNumber + ", email=" + email + "]";
    }
}

And here is the pseudocode:

class Person
    data: name, address, phoneNumber, email
    method toString: return name, address, phoneNumber, email

class Student extends Person
    data: status
    method toString: return status, name, address, phoneNumber, email

class Employee extends Person
    data: office, salary
    method toString: return office, salary, name, address, phoneNumber, email

class Faculty extends Employee
    data: officeHours, rank
    method toString: return officeHours, rank, office, salary, name, address, phoneNumber, email

class Staff extends Employee
    data: title
    method toString: return title, office, salary, name, address, phoneNumber, email

In the Java code, each class has its own data fields and a toString method that returns a string representation of the object. The toString method is overridden in each subclass to include the data fields of the superclass and the subclass. The pseudocode follows the same structure as the Java code.
