- Books can come in various formats, like paper books, audio books, ebooks, etc. Create a generic classBook that has as common attributes the title, the year of publication, and the author. The constructor of thisclass should instantiate all three attributes. Override the toString method of class Book that returns a stringthat contains the values of its attributes. Create a subclass PrintBook that extends Book with attributesPublisher and ISBN. Create another subclass AudioBook which has the book’s size (in MB), its playlength and the playback artist’s name as attributes. Both PrintBook and AudioBook classes override thetoString method inherited from Book. Write a Java application to demonstrate the usage of this hierarchy.Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.Part 2: Sorting the WorkOrders via dates Another error that will still be showing is that there is not Comparable/compareTo() method setup on the WorkOrder class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the WorkOrder class. The compareTo() method will take a little work here. We are going to compare via the date of the work order. The dates of the WorkOrder are saved in a MM-DD-YYYY format. There is a dash '-' in between each part of the date. You will need to split both the current object's date and the date sent through the compareTo() parameters. You will have three things to compare against. You first need to check the year. If the years are the same value then you need to go another step to check the months, otherwise you compare them with less than or greater than and return the corresponding value. If you have to check the months it would be the same for years. If the months are the same you…
- Which is true? Group of answer choices A class can implement multiple interfaces A class can inherit from multiple classes A class can implement only one interface An interface can implement multiple classesPlease do it in JavaScript or C# 1) Design and implement the class structure for a drawing application. A drawing is made up of a canvas that contains a collection of three different shapes: circles, lines, and boxes. Each shape can be drawn by calling a Draw() method for that shape. The canvas class should also have a draw method that draws all of the shapes it contains. You don’t have to actually draw anything on a screen; you can simulate drawing by writing a message to the console.For example, the code snippet: canvas.Draw();Drawing a circle at...Drawing a line at...etc. (For each shape on the canvas) 2)(Bonus) Consider re-writing the above answer (#1) differently where the canvas does not contain the shapes, but is able to draw any of the three shapes passed to it. Re-design canvas.Draw() if you need to. Your main() program should ask for user input on what shape to draw. Ask once, draw, then exit.could produce something like the following output to the console:Java program * Interfaces 1. Modify the class Rectangle to implement the Comparable interface, as shown in the following UML class diagrams. Apply the required changes in the class’s header.2. Then, in the Rectangle class override the method compareTo(), so if this object’s area is greater than the specified (given through the parameter) object’s area return 1, if it is less than return -1, and 0 otherwise. 3. Create a test class named Test2. Then complete the following tasks: a. Create an ArrayList and add to it 4 Rectangle objects with different width and height values. b. Print out the elements of the ArrayList. c. Sort the elements of the ArrayList using the static method sort of the class java.long.Collections. This would be possible only, if you implemented the method compareTo() correctly in the Rectangle class. d. After sorting the elements of the ArrayList, print the elements again. 4. Run the Test class. Here is the rectangle's class program public class Rectangle extends…
- Implement the following in the .NET Console App. Write the Bus class. A Bus has a length, a color, and a number of wheels. a. Implement data fields using auto-implemented Properies b. Include 3 constructors: default, the one that receives the Bus length, color and a number of wheels as input (utilize the Properties) and the Constructor that takes the Bus number (an integer) as input.please code in python Answer the following questions about this Dog class: [refer image for dog class] 1. Construct an instance of the Dog class whose name is Snickers and was born in2011 and assign that instance to a variable called myDog.2. Call the bark method so that myDog barks 3 times.3. Add a method to the Dog class called isPuppy that returns True if the dog is lessthan 1 year old.4. Add the __str__ method to the Dog class. It should return a string that includesthe dog’s name and age.1. Write a Graph class in Java. This class should represent undirected graphs. You can choose one of the representationsfrom graph exercises, eg object model, sets of nodes and edges, adjacency matrix, or soon, whichever you feel most comfortable with.● Include comments in your Java file to explain how nodes and edges are represented.● Assume that only one edge can exist between two nodes.● Assume that it is possible to have an edge connecting a node to itself, ie that a nodecan be connected to itself via an edge.● Because edges are undirected, an edge between v and w is also one between w and v.● Your constructor method should take one parameter: the number of nodes of thegraph. Add a method to your class: boolean addEdge that takes two parameters, v andw (representing two modes v and w which are connected together by the edgebeing added). If successful, the method should return true. The method should return false when it isunsuccessful, which is in the following cases: the edge is…
- Draw the UML class diagrams for the following classes: An abstract Java class called Person that has the following attributes: a String called idNumber a Date called dateOfBirth representing the date of birth. a String for name A class called VaccineRecord with the following attributes: an enum called type of VaccineType a Date called date a String called batchCode A class called Patient that extends the Person class and has the following attributes and behaviours: an ArrayList that contains VaccineRecord objects called vaccinationRecord a public method called vaccinate that takes a VaccineRecord with the following signature: public void vaccinate(VaccineRecord vaccineRecord); a public boolean method called isVaccinated that returns whether or not the Patient has had a vaccine. A MedicalPractitioner class that extends the Person class and has the following attributes and behaviours: a String called licenseCode a public method called vaccinatePatient that takes as a…Javascript Create an object, Gremlin, that extends the Monster interface and takes the same argument language. Gremlins inherits how a monster eats. Gremlins speaks differently. Gremlins replace each word in a sentence with its only known language, "gar". For example, if the sentence is "I like chicken", the speak() method will turn it into "gar gar gar". class Monster { constructor(language){ this.language = language; this.stomach = Array(); } // takes a food_item STRING and returns everything eaten so far ARRAY eat(food_item) { this.stomach.push(food_item); } // takes in a sentence STRING and returns the passed in sentence STRING with no change speak(sentence) { returnsentence; } }Java Programming Create your own class that illustrates the use of encapsulation. Make sure to include at least one setter and one getter for the class
