1) Define a Person class containing two private attributes: last name, first name. Provide this class with a constructor allowing the initialization of its attributes and a method that displays the last name and first name of a person: void display (). 2) Define a Customer class inheriting from the Person class and having a private attribute: numidentity. Provide this class with a constructor allowing you to create a customer from their last name, first name and identity card number and a method: • void display() which displays the last name, first name and ID number of a customer. 3) Define an Owner class inheriting from the Person class and having two private attributes: name of the video club (nomclub), address of the club (adrclub).

Create a class named 'Member' having the following members: Data members 1 - Name 2 - Age 3 - Phone number 4 - Address 5 - Salary It also has a method named 'printSalary' which prints the salary of the members. Two classes 'Employee' and 'Manager' inherits the 'Member' class. The 'Employee' and 'Manager' classes have data members 'specialization' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a manager by making an object of both of these classes and print the value you assigned.
Which of the following statements are correct? (Select all that applies.) Group of answer choices a) Inheritance is the process by which one object can acquire the properties of another object. b) "super" is used to access the method or member variables from the parent class. c) Constructors are used to initialize a newly created object. d) Method overriding occurs when a child class declares a method that has the same type of arguments as a method declared by one of its parent classes. e) An object that has more than one form is referred to polymorphism.
Create a class called Employee that contains two attributes: name and number. Next, write a class named Production Worker that is a subclass of the Employee class. The Production Worker class should add extra attributes called shift_number (an integer, either 1 or 2) and pay_rate. Write the appropriate accessor and mutator methods for each class. Once you have written the classes, write a program that creates an object of the Employee class and an object of the Production Worker class and prompts the user to enter data for each of the object's data attributes. Store the data in the object, then use the object's accessor methods to retrieve it and display it on the screen.
Write a class named Employee that has the following fields:• name. The name field references a String object that holds the employee’s name.• idNumber. The idNumber is an int variable that holds the employee’s ID number.• department. The department field references a String object that holds the name ofthe department where the employee works.• position. The position field references a String object that holds the employee’sjob title.The class should have the following constructors:• A constructor that accepts the following values as arguments and assigns them to theappropriate fields: employee’s name, employee’s ID number, department, andposition. • A constructor that accepts the following values as arguments and assigns them to theappropriate fields: employee’s name and ID number. The department and positionfields should be assigned an empty string (""). • A no-arg constructor that assigns empty strings ("") to the name, department, andposition fields, and 0 to the idNumber field.…
A class named CafeService contains • Two data members i.e. the orderID and the price of food item(s) served by • A no-argument constructor to initialize both data fields with default values of “ord#0”, 0.0• A parameterized constructor to initialize all data fields with user-defined valuesDerive a class named StaffService from the class CafeService that holds the following:• Two data members i.e. o serviceFee, o the cabinNumberto which the service has been made• A function named totalCharges that returns total cost of an order (including serviceFee + price of food item(s) served)• A parameterized constructor, which requires arguments for all of its own data fields as well as for the data fields of base class• A member function named display() to show all the details of an order including orderID,price, and totalChargesIn the main() function, instantiate an object of class StaffService object and test the implementation of both classes through this object.
Write a class called Bicycle, which contains two attributes, gear, which describes the type of gear the bicycle has, and speed, the max speed the bicycle can reach. Write a class called MountainBike which inherits Bicycle and has one extra attribute, which is the seatHeight. Write a main function in which define an object of type MountainBike that has a manual gear, speed of 20, and seat height of 10. Then print the object status.
