The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. Both classes have these attributes: author: Stringtiltle: Stringisbn : String- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the author’s name (we assume that all names are at least three letters long), and c is the last character of the isbn.- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see samplerun…

USING JAVA: Part A) Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An Appointment has a description (for example, “See the dentist”) and a date. Write a method,                                           occuresOn(int year, int month, int day) The check whether the appointment occurs on that date. For example, for appointment, you must check whether the day of the month matches. This fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Part B) Improve the appointment book by giving the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.

In this question, we will bake a class. Create a class Cake , with the following instance attributes: • name (a string) • ingreds (a list of strings) • price (a float) The Cake class has also the following methods: • Write a constructor that takes as input a string indicating the cake name, and a list of strings indicating the cake ingredients. (No docstring needed.) The constructor uses these values to initialize the attributes accordingly. Note that each cake should be assigned a random price between $10.00 (inclusive) and $15.00 (exclusive). You may import random . Moreover, a cake must contain at least three or more ingredients. If this is not the case, the constructor should raise a ValueError . For this constructor, do not worry about making a copy of the input array. You can simply copy the reference received as input into the corresponding attribute. 1 • Write a method (including docstring) called __str__ which returns a string containing the name of the cake and its price…
