- An enumeration can contain public constant variables O True O False An interface can extend as many interfaces as the programmer wants O True O False An abstract class must contain at least 1 abstract method O True False› Create a student class in java Having 2 instance variables: int rollno; String name • Have 2 methods insertRecord() displayInformation() ▸ Create two objects of Student class > Initializing the value to these objects by invoking the insertRecord method on it. ▸ Displaying the state (data) of the objects by invoking the displayInformation method.Java - Polymorphism Create a class named “Shape” that has the abstract methods getArea() and getPerimeter(). Create classes named “Rectangle”, “Square”, and “Circle”. Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. For rectangle, create attribute length and width. For square, side. For circle, radius. Inputs 1. Char input for Shape type (R/S/C) 2. Dimensions of specific type of Shape C 5 Sample Output Shape(R/S/C): R Length: 10 Width: 50 Area: 500.00 Perimeter: 120.00
- 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.The file below has the basic code for class Vehicles. Create this class using the procedure explained last time. Divide the code between Vehicle.h, Vehicle.cpp and driver.cpp as in the slides (Inheritance and Composition). Leave the subclasses Automobiles and pulled_vehicles alone for now. Complete the code for the class : 1- Adding a data member vName that will hold the vehicle name 2- defining and implementing two constuctors : default with these values 2 and "legs" for the data members and a parameterized constructor 3- defining and implementing the setters and getters. class Vehicles //base-class { // public members public: int No of_wheels; void set wheels (int w) No_of_wheels = W; } ; int main() Vehicle V1; return 0;Goal 1: Update the Fractions Class Here we will overload two functions that will used by the Recipe class later: multipliedBy, dividedBy Previously, these functions took a Fraction object as a parameter. Now ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer (affecting numerator/denominator of the returned object). For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class Now add a private member variable of type int to denote the serving size and initialize it to 1. This means all recipes are initially constructed for a single serving. Update the overloaded extraction operator (<<) to include the serving size (sample output below for an example of formatting) . New Member functions to the Recipe Class: 1. Add four member functions…
- this is for a python class 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt Ex. If a new Product object is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is: Name: Apple Price: 0.40 Count: 3 Ex. If 10…Code: import java.util.*; //Bicycle interface interface Bicycle { abstract void changeCadence(int newValue); //will change value of candence to new value abstract void changeGear (int newValue); //changes gear of car abstract void speedUp(int increment); //increments speed of car by adding new Value to existing speed abstract void applyBrakes(int decrement); } //ACMEBicycle class definition class ACMEBicycle implements Bicycle { int cadence = 0; Â Â int speed = 0; Â Â int gear = 1; //methods of interface public void changeCadence(int newValue) { this.cadence=newValue; } public void changeGear (int newValue) { this.gear=newValue; } public void speedUp(int increment) { this.speed+=increment; } public void applyBrakes(int decrement) { this.speed-=decrement; } //display method void display() { System.out.println("Cadence: "+this.cadence); System.out.println("Gear: "+this.gear); System.out.println("Speed: "+this.speed); } } //KEYOBicycle class definition class KEYOBicycle implements…This is for pygame Ball Class: The Ball class inherits from Drawable and it will draw a circle at its current location. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Class
- Write a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbeeImplement the following parking permit class using java It has a dependency on the car class, no need to implement the car class.
