Library Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.
Class Exercise # 1 Create a class hierarchy with base class as Student and derived classes are Part-Time and Full-Time Full-time students will have an extra field to hold two Exam scores Use suitable data structure to hold 15 quizzes scores for each student (part-time or full-time) Create a class Session Use data structure to hold 20 students in a Session, some are part-time, some are full-time Create public methods to calculate average quiz scores per student for the whole class Create public method to print the list of quiz scores in ascending order for one session Create public method to print names of part-time students Create public method to print exam scores of full-time students Main Program Create an instance of Session, populate it with 20 students and dummy scores Call all public methods of Session and capture the output of those methods on console
Problem 2: Route Planning You are on the development team for a Route Planning application. The team has already developed a class named NavigatorApp for storing and displaying the graph representing the road network. This class has a void displayShortestPath() function which takes the source and destination vertices of the trip and displays the shortest route between them. Using the strategy pattern, draw a class diagram of the system which will allow for the NavigatorApp to display the shortest driving, walking, or cycling route when the displayShortestPath() function is called. You can assume that another developer is in charge of making sure the appropriate strategy is correctly set and for calling the displayShortestPath() function Starter code /* Modify NavigatorApp (if necessary) */ class NavigatorApp { private: Graph map; public: void displayMap(Window * window); void displayShortestPath(Vertex source, Vertex destination, Window * window); /* write pseudo code for this function…
java programming language You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is tested – create…
There are two types of data members in a class: static and non-static. Provide an example of when it might be useful to have a static data member in the actual world.
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…
C# languageCreate a class for “Plane” having functionalities (methods) startengine(), fly() and land(). When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details. And then show working object of Plane in main().
Sequence diagram Create a UML sequence diagram that will show your clients how the system’s classes will interact when customers are buying their flight tickets on the booking website. How to create your assignment Review the code responsible for adding a new item. Make a sequence diagram that captures the interactions of objects in the app when a new item is added. Your sequence diagram should contain the following classes: AddItemActivity ItemList Dimensions Item And contain calls of the following methods: onCreate() loadItems() saveItem() Dimensions constructor Item constructor addItem() saveItems() Lastly, the activation of AddItemActivity should start with the call to “onCreate()”
Class: Square Create a class called "Square", which is inherited from“TwoDimensionShape” class. The "Square" class is used to calculate theArea and the Perimeter of square shapes when their side-length is given, or in contrast,finding the side-length of the square when the Area or the Perimeter of the square is given.The specifications of this class are below. Data Members (Attributes): All are private. sideLength: the sidelight (L) of the square. Methods/Operations/Getters/Setters: Default Constructor: when creating an object this constructor must set the side-length of the square by calling the method setSideLength(). Also, this constructor willcall the findArea() and the findPerimeter() in addition to summaryPrint() to calculateand print all needed information. User-Defined Constructor: when creating an object this constructor shouldfind the side-length of the square by calling the method findSquareSideLength()and pass the Area or the…

The main advantage of the encapsulation is that, it provides abstraction between an object and its clients. Select one: O True OFalse Encapsulation is the process of grouping the attributes and method of an object together in a single data structure known as a class Select one: O True O False A constructor is a member variable that is called automatically when an object is created. Select one: O True O False We cannot declare more than one constructor per class. Select one: O True O False on
Object oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…
