Create an Employee Class with the ff: attributes: = String name = double salary = String birthday = __init__(self, name, salary, birthday) = String getDetails() -- returns a String value that represents all the information of the Employee object Create a Manager class that inherits Employee, a Manager will also have the ff: = String department = __init__(self, name, salary, birthday, department) = String getDetails() -- returns a String value that represents all the information of the Manager object Create a Director class that inherits Manager, a Director will also have the ff: = double carAllowance = __init__(self, name, salary, birthday, department, carAllowance) = def playGolf() -- will print a string value '{name of director} plays golf' = String getDetails() -- returns a String value that represents all the information of the Director object Create 2 objects of each class and call their respective getDetails() method. Do not write WET codes, be sure there's no…
Polymorphism : Write a driver program that uses a AECar reference variable to point to three different types of classes, showing that inheritance is one mechanism for using polymorphism.
Consider the following code. class Parent { public: int parentPublicvar; protected: int parentprotectedvar; private: int parentPrivatevar; }; class Childi : protected Parent { public: int childPublicvar; }; class Child2 : private Parent { protected: int childProtectedvar; }; class Child3 : public Parent { private: int childPrivatevar; }; class Grandchildi : protected Child3 }; class Grandchild2 : private Child3, public Childi { }; class Grandchild3 : public Childi, public cChild2 { }; Which of the following statements are true? (select all that apply) Child2 can access childPublicVar O Because Child3 uses public inhericance, GrandChild1 can access parentProtectedVar and parentPrivateVar O The code will not compile because GrandChild2 mixes different types of inheritance O If main creates a Parent object p, this object p in main can access parentProtectedVar. O GrandChild1 can access childPrivateVar V GrandChild3 can access parentPublicVar
language: Java Class Inheritance with an abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the…
15. Suppose the class Employee is declared as follows: public class Employee { private String name; private double baseSalary: public void setName(String newName) {...} public void setBasSalary(double newSalary){...} public String getName() {...} public double getSalary({...} } a)Declare a class Manager that inherits from the class Employee and adds an instance variable bonus for storing a salary bonus. Omit constructors and methods. ANS: b) Which instance variables does the Manager class have? c) In the manager class, provide the method overrides the getSalary method from the class Employee so that it returns the sum of the salary and the bonus d) Based on the above question, which methods does the manager class inherit? e) In the manager class, override the getName method so that managers have a before their name (such as *John Smith).
Consider the following inheritance hierarchy: class A{ protected: int x, y; public: int z; }; class B: private A{ private: int a, b, c; public: void set(int x, int y, int z, int a, int b, int c); }; Int main(){ Aobja; B objb; } questions:a) How many data members does B have? Write their names. b) How many of B’s data members are visible in B? Write down their names. c) Which members of B are accessible in main()? How will they be accessed? d) If the protected Access specifier in A is changed to public, then how many members of B will be accessed in main() and how? e) Define the function set() without changing its signature as given above. f) Write a default constructor for the class B that does not have an empty parameter list. g) If the data members of A become private, then how they be initialized? h) Add a static data member in class B. Can we use this pointer with static members? If yes how?

Lab 12. Java Inheritance Use of Inheritance Inheriting Data members and Methods Constructor in inheritance Multilevel Inheritance Exercise: Create a class called Employeewhose objects are records for an employee. This class will be a derived class of the class Person. An employee record has an employee's name (inherited from the class Person), an annual salary represented as a single value of type double, a year the employee started work as a single value of type intand a national insurance number (inherited from the class Person), which is a value of type String. Write another class containing a main method to fully test your class definition. Your class should have a reasonable number of constructors (use both default constructor and constructor with parameters) and accessor methods: 1) to display all people in alphabetical order 2) to display only employees in alphabetical order 3) to find name of a employee based on national insurance number 4) to filter for…
