Goal 1: Update the Fractions Class 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. 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 Add a private member variable of type int to denote the serving size and initialize it to 1. Update the overloaded extraction operator (<<) to include the serving size. New Member functions to the Recipe Class: 1. Add four member functions get the value of each of the member variable of the Recipe class: getRecipeName(), getIngredientNames(), getIngredientQuantities(), getServingSize() They return the value of the respective member variables. 2. Add and implement a member function that scales the current recipe to a new serving size. The signature of this function is: void scaleRecipe(int…

Summary In this lab, you create a derived class from a base class, and then use the derived class in a Python program. The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status. Instructions Open the file named Motorcycle.py. Create the Motorcycle class by deriving it from the Vehicle class. Call the parent class __init()__ method inside the Motorcycle class's __init()__ method. In theMotorcycle class, create an attribute named sidecar. Write a public set method to set the value for sidecar. Write a public get method to retrieve the value of sidecar. Write a public accelerate method. This method overrides the accelerate method inherited from the Vehicle class. Change the message in the accelerate method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast". Open the file named MyMotorcycleClassProgram.py. In the…

Inheritance, Polymorphism, ArrayLists, Throwing Exceptions The UML diagram below shows a set of classes designed to represent a music collection from 1995. The constructors and methods all function in the standard way, except: The equipmentRequired method should return “Record Player” or “CD Player” as appropriate.The getAlbum method of the NinetiesMusicCollection class accepts an index and returns the corresponding Album object. This method throws an IllegalArgumentException if the index is out of range. (This is the only exception you have to throw anywhere in your code.)In the NinetiesMusicCollection constructor, you can assume the ArrayList<Album> object passed as an argument is not null . Don’t worry about privacy leaks.Implement this set of classes in Java. Note the italics on the Class name “Album” and the method name “equipmentRequired” in the Album class.
