Design a class named Person and its two subclasses named Student and Employee. Design two more classes; Faculty and Staff and inherit them from Employee. The detail of classes is as under: A person has a name, email address, phone number and address. A student has a status (String). An employee has an office, salary, and date hired A faculty member has office hours and rank A staff member has a title. Create display method in each class. Also create getter, setter and default constructor in above task.

Java Type the set up for a Class named Student with the following data fields, name, idNumber, gpa, address, and age. Include get and set methods for each data field.

C- Create the sub class UsedBook  that is derived from the super class Book and has the following instance variables, constructor, and functions: title ( String) isbn ( String) authors (String) publisher (String) edition ( int) published_year (int) price_new (double) // the price of the book if it is new age (int)  // how old the book is in years Constructor that takes all of the above variables as input parameters.  set/get functions calculate_price method // the price is calculated as  price_new * (1- 0.10*age) print function that prints all information related to the old book.   D- Create the Testing class that has the main method and does the following: aa- Use the constructor to create instance of NewBook class and name it as new. Call compute_price function. bb- Use the constructor to create instance of  usedBook class and name it used. Call compute_price function. cc- Print the related information of new and used objects using print functions. Use this following code:   class…

Need help with c++ (1) Define the class ContactNode per the following specifications: Private data members string contactName string contactPhoneNumber ContactNode* nextNodePtr Constructor with parameters for name followed by phone number  Public member functions GetName() - Accessor GetPhoneNumber() - Accessor  InsertAfter()  GetNext() - Accessor PrintContactNode() Ex: If the name is Roxanne Hughes and the phone number is 443-555-2864, PrintContactNode() outputs: Name: Roxanne Hughes Phone number: 443-555-2864 (2) Define main() to read the name and phone number for three contacts and output each contact. Create three ContactNodes and use the nodes to build a linked list. (1st attached image) (3) Output the linked list using a loop to output contacts one at a time. (2nd attached image) Provided template: #include <iostream>using namespace std; class ContactNode {public:   /* Declare member functions here */   private:   /* Declare data members here */   }; /* Define…

C++ Assignment---This is an unfinished code please complete it. Make changes if necessary. Upvote for finished working code. Objectives • To apply knowledge of classes and objects Instructions Implement all of the following, each in a separate Visual Studio project (and/or solution). 1. Define a class called CounterType to implement a simple counter. The class must have a private field (data member) counter of type int. You must also provide methods (member functions), including the following: a. A constructor to set the counter to the value specified by the user b. A constructor to set the counter to 0 c. A method to allow the user to set the counter to a value they specify d. A method to increment the counter by 1 e. A method to decrement the counter by 1 Your code must ensure the value of counter is never negative. If the user calls a method to attempt to make the counter negative, set the counter to 0 and print out an error to the user (e.g., “The counter must not be negative.”) Do…

T/F 3. Any Java class must have a main method, which is the first method that is called when the Java class is invoked.
