For each of the following two code sketches complete the following three steps: Use abstraction and information hiding to improve the design of the code sketch. Your answer should be in form of a code sketch (i.e., make the design clear by providing class names, method names, and examples of how classes and objects will be used). Do not construct an entire detailed program. Describe the negative consequences of poor use of abstraction and information hiding in each code sketch. Describe how your use of abstraction and information hiding avoids the negative consequences listed in the previous step. class Vehicle { } public enum FuelType { DIESLE, ELECTRIC, HYDROGEN, LNG, JET_FUEL } public FuelType fuelType; public void add Fuel (double amount) { if (fuelType == FuelType.DIESEL) { // code for adding diesel fuel... } else if (fuelType == FuelType.ELECTRIC) { // code for adding electric fuel... } else if (fuelType == FuelType.HYDROGEN) { // code for adding hydrogen fuel... } else if…
A library wants to manage its collection of books and authors more efficiently. They would like to create a Python program to help with this task. The following requirements need to be implemented: Create an Author class with the attributes: name, dob (date of birth), and nationality. The class should have a __str__ method to represent the author in a user-friendly format. Create a Book class with the following attributes: title, author (an instance of the Author class), publication_date, and price. Also, include a class variable all_books that keeps a list of all book instances created.The Book class should have: A __str__ method to represent the book in a user-friendly format. A __eq__ method to compare two books. Two books are considered the same if they have the same title and author. A __lt__ method to compare two books based on their publication dates. A class method get_all_books that returns a list of all books in the library. A static method most_expensive_book that takes…

In Python write an address book program using object oriented design, you would need at least two things: An “address book” class. A class that will store information about a “person”. Using knowledge of classes, and thinking constructively about the task assigned with object-oriented design in mind. Requirements: A class named `Person`. Class constructor requires first, middle and last name of your person. Class method `set_email` must exist to set the person’s e-mail address, e.g.` "kirk@starfleet.org".` Class method `get_info` that returns a string formed from a person’s first, middle, last names and e-mail address, in this exact form: `"James Tiberius Kirk <kirk@starfleet.org>".` Class method `__str__ that returns the same string as the `get_info` method. A class named `AddressBook`. It must do the following: No class constructor arguments are required, though you should consider some internal data structures for initialization. Class method…

Describe ways to reduce the cases of coupling in following systems.a) Class CourseSection has public class variables called minClassSize and maxClassSize. These are changed from time to time by the university administration. Many methods in classes Student and Registration access these variables.b) A user interface class imports a large number of Java classes, including those that draw graphics, those that create UI controls and a number of other utility classes.c) A system has a class called Address. This class has four public variables constituting different parts of an address. Several different classes, such as Person and Airport manipulate instances of this class, directly modifying the fields of addresses. Also, many methods declare one of their arguments to be an Address.
Instructions: Implement the Java class Customer by following the UML class diagram provided below. Implementation details: The class constructor must receive the arguments in the following order: String firstName, String lastName, String address, String cardNumber, int pin, String username The password must be generated inside the class constructor by the class method generatePassword(). The password to be generated must meet the following criteria: Must have at least one numeric character. Must have at least one lowercase character. Must have at least one uppercase character. Must have at least one special symbol among @#$% Password length to be generated is fixed and equal to 12. Do please use SecureRandom() class to achieve randomness during password generation. toString() return value format must be as follows:Customer [firstName='John', lastName='Monkey', cardNumber='11336688', pin='1234', username='j.monkey', password='zF$7zR#1lFAo', address='453 Manin st,…

Design, implement and test a class that can be used to hold information about a musical note. Test it with an appropriate driver program. DESIGN REQUIREMENTS A programmer MUST be able to set and retrieve the length of the note and the value of the note. [[ this means you must have setter and getter methods for your data fields.]] The length of a note may be a sixteenth note, eight note, quarter note, half note, or a whole note, [[ Feel free to code this however you like with a string, an integer, an enum... whatever you feel is best ]] The note's value is an integer. It is specified by counting how far the note lies above or below the A note that orchestras use in tuningLinks to an external site. In counting "how far", you should count every key, both the white and black notes on a plano. So the A note above middle C would have a value of 0. The A note one octave above that would have a value of 12. The default constructor should set a note to a A440 (an A note of frequency 440Hz)…
