Textbook Question
Chapter 10, Problem 9E
Write a
full name—the first and last names separated by a space. Then perform the following
• Create two child classes of Salesperson: Real EstateSalesperson and Girl Scout. The Real EstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are initialized to 0), and a commission rate field required by the class constructor. The Girl Scout class includes a field to hold the number of boxes of cookies sold, which is initialized to 0. Include properties for every field.
• Create an interface named ISell able that contains two methods: SalesSpeech() and MakeSale(). In each Real EstateSalesperson and Girl Scout class, implement SalesSpeech() to display an appropriate one- or two-sentence sales speech that the objects of the class could use.
In the Real Estatesalesperson class, implement the MakeSale() method to accept an integer dollar value for a house, add the value to the Real EstateSalesperson’s total value sold, and compute the total commission earned. In the Girl Scout class, implement the MakeSale() method to accept an integer representing the number of boxes of cookies sold and add it to the total field.

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.
Question 6
Create a set of classes and interface for the following scenario:
Define an interface called Classical Music, which contains a get Year method that
returns the year the classical album released.
Create an abstract class Called CD. This class contains the title as String, and
playingTime as integer (e.g. 60 minutes). Include a constructor to initialize all the data
fields. Create an abstract method called printPlayingTime to show the CD playing
details. Make sure all the data fields can be accessed directly from the child classes.
Create a class called Album that inherits from the CD and Classical Music. Include
a data field called year as integer type. Create a constructor to initialize all the data
members. Override the getYear method to return the released year. Override the
printPlayingTime method. If the CD title is more than 10 characters, this method
will print the first 10 characters, followed by the three ellipse dots and the playing
time. For example:

- 1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten.

- Construct a Time class containing integer data members seconds, minutes, and hours. Have the class contain two constructors: The first should be a default constructor having the prototype Time(int, int, int), which uses default values of 0 for each data member. The second constructor should accept a long integer representing a total number of seconds and disassemble the long integer into hours, minutes, and seconds. The final member method should display the class data members.arrow_forwardCreate a class named Poem that contains the following fields: title - the name of the poem (of type String) lines - the number of lines in the poem (of type int) Include a constructor that requires values for both fields.

- 1- 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_forwardIn Java Programming, 2 class needs a no-arg constructor and a constructor that initializes all fields with data (The ProductionWorker class constructor should receive data for the Employee class fields as well). I need help to create a method within the Employee and ProductionWorker classes called displayInfo. (displayInfo accepts no arguments and returns void). To display the data for each constructor, the demonstration class will call the subclass displayInfo method and it will call the superclass displayInfo method. User input is not required for the demonstration class. Have a class named "Employee" with the following fields: - Employee Name - Employee Number in format XXX-L, X = digit w/ range 0-9 & L = letter w/ range A-M. - Hire Date Then one or more constructors and the appropriate accessor and mutator methods for the class.

The Insurance class contains a get method for each field; it also contains two abstract methods named setCost() and display(). The Life class setCost() method sets the monthly fee to $36, and the Health class sets the monthly fee to $196.

- Create an abstract class called Shape with the protected member String shapeName. It should have two public abstract methods getArea and getVolume. Finally, it should contain a public String method called getName which returns the shapeName. You should create a Circle class, Square class, Rectangle class, Triangle class which extend the Shape class. Each class should contain the necessary private variables. For example, a square has a side. The area and the volume can all be derived from the side value so the only private variable necessary for the square class is the side. The circle requires a radius. The triangle requires a base, length and a height. Finally, the rectangle requires length, height and width. The classes should also contain constructors and appropriate implementations of the two abstract methods getArea and the getVolume. **Shape Calculator** Enter 1 for a Circle Enter 2 for a Square Enter 3 for a Rectangle Enter 4 for a Triangle Enter 5 to Exit You should use a…arrow_forwardWrite a graphical application that contains a class named RV whose objects are the recreational vehicle designed and digitized as described in Knowledge Exercises 20 and 21 (you can design your version as well.

It should include a three-parameter constructor, a toString method, a method to input the values of all of an object’s data members, and a show method to draw the RV at its current (x, y) location. b) Progressively implement and test the RV class by adding a method and verifying it before adding the next method. A good order to add the methods to the class is the three-parameter constructor, followed by the toString method, the show method, and finally the inputmethod. The client code should create an RV object using the three-parameter constructor to test all of the methods as they are progressively added to the…arrow_forwardTo determine if two objects in a class are equal, we should NOT use "==".
