- 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 consoleProblem 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…
- 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.Data Structuresjava 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…
- 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…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()”Using Visual Studio C# Language Note: not a User Input
- Define the struct studentType to implement the basic properties of a student. Define the class studentType with the same components as the struct studentType, and add member functions to manipulate the data members. (Note that the data members of the class studentType must be private.) Write a program to illustrate how to use the class studentType. Struct studentType: struct studentType { string firstName; string lastName; char courseGrade; int testScore; int programmingScore; double GPA; }; An example of the program is shown below: Name: Sara Spilner Grade: A Test score: 89 Programming score: 92 GPA: 3.57 *************** c++ code please This is the code I have but I keep getting error #include<iostream> using namespace std; class studentType { private: string firstName; string lastName; char courseGrade; int testScore; int programmingScore; double GPA; public: studentType(string f, string l, char CG, int TS, int PS, double gpa) { cout<<"Name:…Object Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game.
