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…
The Point2D should store an x and y coordinate pair, and will be used to build a new class via class composition. A Point2D has a x and a y, while a LineSegment has a start point and an end point (both of which are represented as Point2Ds). class Invariants The start and end points of a line segment should never be null Initialize these to the origin instead. Data A LineSegment has a start point This is a Point2D object All data will be private A LineSegment also has an end point. Also a Point2D object Methods Create getters and setters for your start and end points public Point2D getStartPoint() { public void setStartPoint(Point2D start) { Create a toString() function to build a string composed of the startPoint’s toString() and endPoint’s toString() Should look like “Line start(0,0) and end(1,1)” Create an equals method that determines if two LineSegments are equal public boolean equals(Object other) { if(other == null || !(other instanceof LineSegment)) return…

Lab 10 Using an interface to share methods It is often the case that two or more classes share a common set of methods. For programming purposes we might wish to treat the objects of those classes in a similar way by invoking some of their common routines.For example, the Dog and Cat classes listed below agree on the void method speak. Because Dog and Cat objects have the ability to “speak,” it is natural to think of putting both types of objects in an ArrayList and invoking speak on every object in the list. Is this possible? Certainly we could create an ArrayList of Dog that would hold all the Dog objects, but can we then add a Cat object to an ArrayList of Dog?Try running the main program below as it is written. Run it a second time after uncommenting the line that instantiates a Cat object and tries to add it to the ArrayList. import java.util.*;public class AnimalRunner{ public static void main(String[] args) { ArrayList<Dog> dogcatList = new ArrayList<Dog>();…
Implement a nested class composition relationship between any two class types from the following list: Advisor Вook Classroom Department Friend Grade School Student Teacher Tutor Write all necessary code for both classes to demonstrate a nested composition relationship including the following: a. one encapsulated data member for each class b. inline default constructor using constructor delegation for each class c. inline one-parameter constructor for each class d. inline accessors for all data members e. inline mutators for all data members
Indications:Person is an abstract class containing the abstract method Print().In Teacher and Student the method print() will print the information of either Teacher or Student.Write the class university corresponding to the following UML diagram. It contains three attributes.Tab is an array of Person. sizeTab is the size of Tab. The attribute n represents the number of elements added to the tab. When the tab is empty n is equal to 0.The constructor University(sizeTab) will initialize the different attributes and allocate the memory to the array Tab.addPerson(p:Person) will add the new person to Tab. The method printAll() will print all the information of the Persons inside Tab.Write the main method. Create three Teacher and three Student and add them to University Object and print them all.
Object passing checklist1. Go over each member function and add the const keyword after their declaration ifthey do not modify any of the class' member variables.2. When accepting objects as parameters, prefer to pass them by reference. Add reference declarator (& before the identifier name of an object parameter.3. If the member function does not modify the parameter, make the parameter constantby using the const keyword. apply the Object Passing Checklist. Modify food.h and volunteer.h to useobject references. Add const and & keywords in the appropriate places of the code.
The total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…

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 frisbee
