• 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.

- 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. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…arrow_forwardJAVA - USING CONSTRUCTORS Create a class named House that includes data fields for the number of occupants and the annual income as well as methods named setOccupants(), setIncome(), getOccupants() and getIncome() that set and return those values respectively. Additionally, create a constructor that requires no arguments and automatically sets the occupants field to 1 and income field to 0. Create an additional overloaded constructor . This constructor receives an integer argument and assigns the value to the occupants field. Create a third overloaded constructor this time, the constructor receives 2 arguments, the values of which are assigned to the occupants and income fields respectively. Create another class named I_house that instantiates the House class and see if the constructors work correctly.arrow_forwardThis is the question - Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum. The Rock class contains the following fields: sampleNumber - of type int description - A description of the type of rock (of type String) weight - The weight of the rock in grams (of type double) Include a constructor that accepts parameters for the sample number and weight. The Rock constructor sets the description value to "Unclassified". Include get methods for each field. Create three child classes named IgneousRock, SedimentaryRock, and MetamorphicRock. The constructors for these classes require parameters for the sample number and weight. Search the Internet for a brief description of each rock type and assign it to the description field using a method named setDescription inside of the constructor. This is the code I have, the program does not like at all what I have - import java.util.*; public class DemoRock { public static…arrow_forward

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_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_forward
- In 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. Also, another class named "ProductionWorker" that extends "Employee" class. The "ProductionWorker" class should have the following fields to hold…arrow_forwardBuild a class named car. This class is defined as follows: It has the fields: Car ID, Car model , Car make, Car color, Car year. Build a constructor that accepts the five parameters (Car ID, Car model , Car make,Car color, Car year). Override the method toString() to return the string representation of Car ID, Carmodel , Car make, Car color, Car year.arrow_forwardCreate 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_forward
