(CarbonFootprint Abstract Class: Polymorphism) Using an abstract class with only pure virtual functions, you can specify similar behaviors for possibly disparate classes. Governments andcompanies worldwide are becoming increasingly concerned with carbon footprints (annual releasesof carbon dioxide into the atmosphere) from buildings burning various types of fuels for heat, vehicles burning fuels for power, and the like. Many scientists blame these greenhouse gases for the phenomenon called global warming. Create three small classes unrelated by inheritance—classesBuilding, Car and Bicycle. Give each class some unique appropriate attributes and behaviors thatit does not have in common with other classes. Write an abstract class CarbonFootprint with onlya pure virtual getCarbonFootprint method. Have each of your classes inherit from that abstract classand implement the getCarbonFootprint method to calculate an appropriate carbon footprint forthat class (check out a few websites that…

Problem (Online Address Book): Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType with following members and methods: firstname, lastname, and accessors and mutators, print to display, and constructors.  Define a class dateType for month, day and year as members with its accessors, mutators, and constructors) Design a class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information.…

use java (ArrayList, inheritance, polymorphism, File I/O and basic Java) Student class: First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: A first name (given name) A last name (family name/surname) Student number (ID) – an integer number (of type long) The Student class will have at least the following constructors and methods: (i)  two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables of Student. (ii)  only necessary set and get methods for a valid class design. (iii)  a reportGrade method, which you have nothing to report here, you can just print to the screen a message “There is no grade here.”. This method will be overridden in the respective child classes. (iv)  an equals method which compares two student objects and returns true if they…

(Package Inheritance Hierarchy) Package-delivery services, such as FedEx® ,DHL®and UPS® ,offer a number of different shipping options, each with specific costsassociated. Create an inheritance hierarchy to represent various types of packages. Useclass Package as the base class of the hierarchy, then include classes TwoDayPackageand OvernightPackage that derive from Package.Base class Package should include data members representing the name, address, city,state and ZIPcode for both these sender and the recipient of the package, in addition todata members that store the weight (in ounces)and cost per ounce to ship the package.Package’s constructor should initialize these data members. Ensure that the weight andcost per ounce contain positive values. Package should provide a public memberfunction calculate Cost that returns a double indicating the cost associated with shippingthe package. Package’s calculate Cost function should determine the cost bymultiplying the weight by the cost per…

What are the three things you need to do when working with classes that include pointer variables as member variables?

Code in JAVA and please see attached images on specifications The Inheritance hierarchy is as follows:  (Be sure to create this hierarchy correctly and efficiently; taking advantage of inheritance, polymorphism and exception handling concepts discussed in previous modules) A company pays its personnel on a weekly basis.  The personnel are of 4 types:  FixedWeekly personnel are paid a fixed amount regardless of the number of hours workedByTheHour  personnel are paid by the hour and receive overtime pay for all hours worked in excess of 40PercentOfSales personnel are paid a percentage of their salesFixedWeeklyPercentOfSales personnel receive a fixed amount plus a percentage of their sales.All variables are private, thus all of them will have public getters and setters Create a class called Personnel.  This class will represent the general concept of all personnel.  All 4 types of personnel are considered Personnel.  FixedWeeklyPercentOfSales personnel are considered to be PercentOfSales…
