Part-2 (Encapsulation, Inheritance, Polymorphism)Create a Java project that demonstrates various object oriented concepts you have learned so farin this course (encapsulation, inheritance and polymorphism). To do this, create a super class andat least 2 subclasses. You can either do multilevel inheritance or hierarchical inheritance in thisto complete this part-2 task.The super class will have following properties/functionalities:a) Create a total of 3 member variables for the class, selecting the appropriate data typesfor each field.b) Include an argument constructor in this Class, that will initialize all data fields.c) Encapsulate this Class.The two subelasses will have below properties/functionalities:a) One of the subclasses will have at least one member variable and other subclass with atleast two member variables.b) Have two constructors in each subclass:• One constructor for initializing only super class dataAnother constructor will initialize both super and subclass data.c) Encapsulate the subclasses.d) You should include overloaded methods in any of the classes you have created(superclass or subclass).e) Override the toString( ) method in each of your Classes.f) Override the equals( ) method in each of your Classes.The test elass [with the main ( ) method] will perform below tasks:a) Create objects of superclass and each subclass types invoking all constructors and Drawthe object diagram for each of the object created.b) Use setter methods to fill missing data in all objects.c) Generate outputs demonstrating overloading, overriding outputs.d) Create object of subclass [actual type] and store it in superclass object [declared type].e) Generate output for instanceof operator.f) Do object casting (show both implicit and explicit)g) Generate output for constructor chaining [using this and super keywords]Note:1) Draw object diagrams wherever possible and necessary to show the state of the objectscreatedInclude the below in your project report:• The UML diagram of all Classes.• Screenshots of all output generated from the application.

Overview Construct a hierarchy of classes representing savings and checking accounts as well as a means to ‘filter’ account objects. Account Classes Your solution will consist of 4 account classes as described below. It is your responsibility to define the exact relationship among those classes and translate that relationship into source code structure. There is a correct structure; the skeleton must be modified to reflect the correct relationships.  Account – represents a general account with basic operations such as deposit, withdraw, etc.  Savings – represents a savings account that must maintain a minimum balance.  Checking – represents a checking account that has no minimum balance (this means a zero balance).  CappedChecking – represents a checking account that disallows a balance above a particular maximum value. Linking Accounts A bank or credit typically allows a user the ability to link accounts together. That is, I might wish to link my checking account with my savings…
The language is C++ for visual studio code 2017. Create a program that uses the follwing: A main function that utilized minimum code to drive the program. Coding details shall be in appropriately-implemented classes. At least three class modules, one class shall be abstract and an associated derived class. At least one example of an overloaded constructor. At least one polymorphic method. At least one pointer and one reference Demonstrate correct use of public, private and protected keywords\
Create a UML Class Model based on the requirements . Your Class Model is to include: All classes Attributes and Attribute Types Associations Multiplicity Primary and Foreign keys Any Inheritance, Composition or Aggregation. Building Maintenance system. A rental property management company wants to develop a ‘Building Maintenance System.’ This system will be used by the company to manage maintenance requests from tenants in the several rental buildings that it manages in the city. Each building has a maintenance manager. The maintenance manager is responsible for creating accounts in the system for each tenant in their building. A tenant can rent multiple apartments within the same building. Tenants can submit maintenance requests using this system. Each maintenance request will have a request ID, category, and description. The maintenance manager manages a maintenance crew in their building. Maintenance crew members can be members of more than one maintenance team. Maintenance crew…

Question 30 Which of the following description is TRUE? Inheritance allows us to define a class based on another class. Child classes receive all the features from the parent class but can NOT have their own additional features. Abstraction means that a method in a parent class can have a number of different implementations in child classes. An interface is a completely abstract class, which contains abstract properties, methods, and variables. The private access modifier makes members accessible only from within the class and hides them from the outside.
You will define three objects class Person, BookAuthor, and Book. Class Person involves a person's identity. Class BookAuthor involves a collection of books or book titles. Class Book involves the number of books in stock , book title and price. Design the three classes: The classes must use an appropriate inheritance relationship. Each class must have a constructor. Each class has at least two private data members and you must include accessors. You must test your classes by creating a BookAuthor object and printing the Person, Book and BookAuthor values from a function you create inside of BookAuthor. Make sure you use the book object correctly and put it inside of BookAuthor. in pytgi
Part-2 (Encapsulation, Inheritance, Polymorphism) Create a Java project that demonstrates various object oriented concepts you have learned so far in this course (encapsulation, inheritance and polymorphism). To do this, create a super class and at least 2 subclasses. You can cither do multilevel inheritance or hierarchical inheritance in this to complete this part-2 task. The super class will have following propertics/functionalitics: a) Create a total of 3 member variables for the class, sclecting the appropriatc data types for cach ficld, b) Include an argument constructor in this Class, that will initialize all data fields. c) Encapsulate this Class. The two subclasses will have bclow properties/functionalitics: a) One of the subclasses will have at lcast one membecr variable and other subclass with at least two member variables. b) Have two constructors in cach subclass: One constructor for initializing only super class data Another constructor will initialize both super and…

1. Driented Programming Design the class Manager that inherits from the Employee Class (defined in Question 1) and contains the two private data members, managedDepartment of integer type and managerAllowance of double type. Add the following public member methods: 1. One constructor without parameters. 2. One constructor with parameters related to managedDepartment and managerAllowance. 3. getManagedDepartment to return the managedDepartment. 4. getManagerAllowance to return the managerAllowance. 5. PrintEmplnfo to display the manager information data on the standard output. I !! public class Manager extends Employee { int managedDepartment; double managedAllowance%3;
