Chapter 7, Problem 4PP
Define a class called Administrator, which is a derived class of the class SalariedEmployee in Display 7.5. You are to supply the following additional instance variables and methods:
An instance variable of type String that contains the administrator's title (such
as "Director" or "Vice President").
An instance variable of type String that contains the administrator's area of responsibility (such as "Production", "Accounting", or "Personnel").
An instance variable of type String that contains the name of this administrator's immediate supervisor.
Suitable constructors, and suitable accessor and mutator methods.
A method for reading in an administrator's data from the keyboard.
Override the definitions for the methods equals and tostring so they are appropriate to the class Administrator.
Also, write a suitable test

2. This question involves the implementation of a fitness tracking system that is represented by the
StepTracker class. A StepTracker object is created with a parameter that defines the minimum
number of steps that must be taken for a day to be considered active.
The StepTracker class provides a constructor and the following methods.
addDailySteps, which accumulates information about steps, in readings taken once per day
activeDays, which returns the number of active days
averageSteps, which returns the average number of steps per day, calculated by dividing the
total number of steps taken by the number of days tracked
The following table contains a sample code execution sequence and the corresponding results.

1. Create a class called Elevator that can be moved between floors in an N-storey building. Elevator uses a constructor to initialize the number of floors (N) in the building when the object is instantiated.
Elevator also has a default constructor that creates a five- (5) storey building.
The Elevator class has a termination condition that requires the elevator to be moved to the main (i.e., first) floor when the object is cleaned up. Write a finalize() method that satisfies this termination condition and verifies the condition by printing a message to the output, Elevator ending: elevator returned to the first floor.
In main(), test at least five (5) possible scenarios that can occur when Elevator is used in a building with many floors (e.g., create, move from one floor to another, etc.).
Hint: Termination occurs when the instance is set to null. You may wish to investigate “garbage collection” for this exercise.
When solving this problem make sure that the user can interact with the…

- 4. Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four data members-a part number (type string), a part description (type string), a quantity of the item being purchased (type int) and a price per item (type int). Your dlass should have a constructor that initializes the four data members. A constructor that receives multiple arguments is defined with the form: ClassName( TypeName1 parameterName1, TypeName2 parameterName2, .) Provide a set and a get function for each data member. In addition, provide a member function named getinvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as an int value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0. Write a class program according to the main.cpp program given below. #include #include invoice #include…arrow_forward1- Create a hierarchy of Java classes as follows: MyRectangle is_a MyShape; MyOval is a MyShape. Class MyPoint: Class MyPoint is used by class MyShape to define the reference point, p(x, y), of the Java display coordinate system, as well as by all subclasses in the class hierarchy to define the points stipulated in the subclass definition. The class utilizes a color of enum reference type MyColor, and includes appropriate class constructors and methods. The class also includes draw and toString methods, as well as methods that perform point related operations, including but not limited to, shift of point position, distance to the origin and to another point, angle [in degrees] with the x-axis of the line extending from this point to another point. Enum MyColor: Enum MyColor is used by class MyShape and all subclasses in the class hierarchy to define the colors of the shapes. The enum reference type defines a set of constant colors by their red, green, blue, and opacity, components,…arrow_forwardImagine a publishing company that markets its works. Create a class publication that stores the title (a string), author (string), pages (int), pulicationDate (string) and price (type float) of a publication. There should be two constructor i.e. default and parameterized. The default Constructor should initialize the data members to 0 or 0.0 or “” if integers, floating point or string respectively. The parameterized constructor should assign user defined values to the data members. The default constructor should be inline while the parameterized constructor should not be inline. There should be an input/get function to input the values to the data members and a Print() to display the contents of the class variables/datamembers. Create two objects of the class named book, and tape. The book should be created with default constructor, while tape with parameterized constructor. Call input/get for book object only. Then call Print() for both the objects to display the contents. Mention…arrow_forward
- 1. Create a properly encapsulated class named Person that has the following: A String instance variable called name. A constructor that takes a String parameter and sets the instance variable. A properly named getter for the instance variable. A correctly overrided equals method which returns true if the name instance variable of the parameter and the reference variable calling the method are equal. (Do not forget the null and class type checks!) Compile your Person class. 2. Create a properly encapsulated class named Employee that inherits from Person and has the following: ● ● ● A String instance variable called office (e.g. "LWH 2222"). A String instance variable called hourlywage (e.g. "$45.15").

It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 Clothing objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a Clothing object whose color was blue, whose display name was work trousers, for a price of 27.99, you could use the getters to print something like this:These work trousers are blue and cost $27.99.Don't hardcode the print statement for full credit, you must use the gettersarrow_forward2. You are to write a program that computes a patient's bill for a hospital stay. different components of the program are The The PatientAccount class The Surgery class The Pharmacy class The main program The PatientAccount class will keep a total of the patient's charges. It will also keep track of the number of days spent in the hospital. The group must decide on the hospital's daily rate. The Surgery class will have stored within it the charges for at least five types of surgery. It can update the charges variable of the PatientAccount class. The Pharmacy class will have stored within it the price of at least five types of medication. It can update the charges variable of the PatientAccount class. The student who designs the main program will design a menu that allows the user to enter a type of surgery and a type of medication, and check the patient out of the hospital. When the patient checks out, the total charges should be displayed.arrow_forward
