15. Suppose the class Employee is declared as follows: public class Employee { private String name; private double baseSalary: public void setName(String newName) {...} public void setBasSalary(double newSalary){...} public String getName() {...} public double getSalary({...} } a)Declare a class Manager that inherits from the class Employee and adds an instance variable bonus for storing a salary bonus. Omit constructors and methods. ANS: b) Which instance variables does the Manager class have? c) In the manager class, provide the method overrides the getSalary method from the class Employee so that it returns the sum of the salary and the bonus d) Based on the above question, which methods does the manager class inherit? e) In the manager class, override the getName method so that managers have a before their name (such as *John Smith).
Most important Class in Customer Relationship Management (CRM) System is indeed Customer. Customer class can have fields: Name, ID, Gender, Contact Number & Address The member functions include the getters and setters for all the member variables and display() function to display the data. Customer - ID: int - Name: String - Gender: String - ContactNumber: String - Address: String +>Customer() +getters and setters +display (): void In the main function, first create two Customer objects and allow the user to enter data in these objects. Secondly, display the data from these objects.
Library Management System Develop a Library Management system for borrowing and returning activities The basic classes could be the main Library, Subscribers, borrowing records, Contents, articles, e.t.c. NB: Contents may include books, journal articles or digital media. Also a subscriber may borrow books for one month, after which a fee accrue until the borrowed item is returned. On the other hand, golden subscribers may borrow for 2 months without fee before fees begin. Provides an interface for the user to: A. Adding/editing/deleting instances belonging to each class, B. Subscriber browsing library contents and select items to borrow. C. Subscriber returning borrowed item and check his balance and pay any late fee if any. D. Admin can print reports of overdue borrowed items.
Object Oriented Programing Consider the following details of all classes: Person Student Employee Administration Dean/HOD A person can be an employee or a student. An employee may have rights of admin officer or of academic officer. These class hierarchies represent multi-level inheritance. However, a Dean or Head of Department(HOD) may have rights to modify the status already defined by an administrator academic officer. Implement all these classes with appropriate data members and proper suitable functions and within the main function, create instances of all classes and test the described working of all these classes
Define a Course base class with the following attributes: number - course number title - course title Define a print_info() method in Course that displays the course number and title. Also define a derived class OfferedCourse with the additional attributes: instructor_name - instructor name location - class location class_time - class time
Problem: Create the class on the UML class diagram. Account + balance: double + interest: double + owner: String +id:int + withdrawal(double amount): double + deposit(double amount): double + calculateNextAmount():double While creating your class: 1) Write the class according to the UML class digram. 2) Encapsulate balance,interest, owner and id values. 3) Create getter, setters for balance and interest. Not for id and customer. So, owner and id will only be obtained while creating the objects. 4) Create constructor for the class. In your main program: 5) Create 5 account objects. 6) Withdraw some amount of Money from the accounts and inform the user about the new amount. If there is no enough Money, user should be informed. (Make validation) 7) Deposit some amount of Money to the accounts. Inform the user about new amount. 8) Calculate new amount of Money for the accounts one year later and write to console.
A. Please draw a class diagram for the following classes and relationships We have classes: Customer, order, address, VIP-customer, customized-order, item and they have the following relations: 1.Customer can make orders 2. Each order contain multiple items 2.Each customer has a mailing address 3.VIP-customer can also make a customized-order which is a special order. 4.Each order will be mailed to the customer's mailing address
Programming Assignment #5 Educational Objectives: After completing this assignment the student should have the following knowledge, ability, and skills: Define a class hierarchy using inheritance Define virtual member functions in a class hierarchy Implement a class hierarchy using inheritance Implement virtual member functions in a class hierarchy Use initialization lists to call parent class constructors for derived class constructors Operational Objectives: Create (define and implement) a base class Shape classes that will inherit this class called Box, Rectangle, Circle, and Triangle Description: Programming Specifications: You will have a base class of Shape which will have an area and perimeter of type double. You must also create acceptable Gets and Sets for the private data items. All of the other classes will inherit this class. You will have a class Square which will have just one length of type double. You should create acceptable Gets and Sets for the one…

*Initial Class Diagram is attached below Refine the UML class diagram so that it demonstrates the following: Classes (using the complex class symbols), Associations (with multiplicities AND association names), Generalizations (if any), and Compositions (if any) Focus ONLY on the following activities within the system: Start a Trip, Reserve a Vehicle, Make a Parking Reservation, Make a Charging Session for a Personal Vehicle, End a Trip or Charging Session, and Submit a Support Ticket for a Vehicle or Station Add the primary key necessary to support any relationships that have a multiplicity of "1" as an attribute in the corresponding class
