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:
Thriller 60…
5. class definition for GameEnemy
Next, we want to start making enemies for our upcoming video game, so we will define a class called GameEnemy.
Every GameEnemy will have a name, an x location, a y location, and a number of hit points (which must be a non-
negative integer ). The_init__ method for GameEnemy will take all of these parameters (in that order) and store them
on the object. GameEnemy also needs a method called healthbar, which will allow us to show that enemy's health bar in
the game. It returns the enemy's name followed by a number of asterisks to show how many hit points it has left. The
exact format is shown below.
Sample runs should look like:
>>> enemy = GameEnemy ("TODD", 100, 200, 5)
>>> enemy.healthbar()
TODD: ******
>>> enemy-%
ence
100
>>> enemy-y
200

- Write a shoe class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "nikes, adidas", "puma") price (e.g., 100, 200,60) Include only one constructor. 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 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 shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230arrow_forwardCreate an abstract class called vehicle. The class should declare the following variables: an instance variable that describes the model - String an instance variable that describes the number - String an instance variable that describes the maker - String an instance variable that describes the price - double an instance variable that describes the year – integer Provide a toString() method that returns the information stored in the above variables. Create the getter and setter methods for each instance variable except price. Provide the necessary constructors. Include an abstract method setPrice(double price) to determine the price for a vehicle. Include an abstract method getColor() to return the color of the vehicle. Create two subclasses called Car and Truck . These subclasses should override the abstract methods setPrice and getColor of class vehicle. Use the following rule for setting the price for a vehicle: car will have a 30% discount per each vehicle truck…arrow_forwardThis is the question I am stuck on - 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 what I am given - import java.util.*; public class DemoRocks { public static void main(String[] args) {…arrow_forward
- Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.arrow_forwardCreates a class Student with 3 attributes: name, id and level. a.

- 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).
