- All of the following are true about a class EXCEPT: Oa function associated with a class is referred to as a subroutine. Oa class created in one source code file can be used in another source code file. Oa class is a blueprint for creating objects. Oa class can contains data, and methods to manipulate the data.Describe how you can use an interface as an alternative to a class to specify the type for a parameter.in the date classOverload the constructor method as the class diagram showsIn the main program, create three objects of class date, one from each of the constructors.In the main program, overload the showdate method to display the date in the following formatsThe date in dd/mm/yy formatThe date in dd/mm formatThe date in “d of month” formatIn the main program, make use of each of the showdate methods, one with each of the created objects.Send your two files, the date file and the main program where you use the date constructor overload and the showdate method overload.
- Classes: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit. Deliverable: Submit your source code and classes on Github (you will be supplied an account) You will also submit a Word document and your code on Canvas. In the document you iwll write a summary of your design…A class variable does not belong to a particular object. It belongs to the entire class. Which field below is an example of a class variable? public class Pizza { private static int numPizzas; private static int numRestaurants; private static double reheatTemperature; private static string foodGroup; private string name; private string[] toppings; private double calories; private double price; } price foodGroup calories nameA cash processing company has a class called Account used to process transactions: Method/Constructor Description public Account (Client c) public boolean process (Transaction t) constaucts an account using client information processes the next transaction, returning true if transaction was approved, false otherwise Account objects interact with Transaction objects, which have many methods including: Method/Constructor Description returns the value of this transaction in pennies (could be negative, positive or zero) public int value() The company wishes to create a slight modification to the Account class that filters out zero-valued transactions. Design a new class called FilteredAccount whose instances can be used in place of an Account object but which include the extra behavior of not processing transactions with a value of 0. More specifically, the new class should indicate that a zero-valued transaction was approved but shouldn't call the process method in the Account class to…
- Exercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the accountIf a member is declared private in a class, can it be accessed from other classes? If a member is declared protected in a class, can it be accessed from other classes? If a member is declared public in a class, can it be accessed from other classes?Using C# language: Programming PLO-2 Measured: Design, implement, and evaluate computer solutions utilizing structured and object-oriented programming methodologies. Design a class named Contractor. The class should keep the following information: Contractor name Contractor number Contractor start date Write one or more constructors and the appropriate accessor and mutator functions for the class.
- INVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…Design a Ship class that has the following members:• A field for the name of the ship (a string).• A field for the year that the ship was built (a string).• A constructor and appropriate accessors and mutators.• A toString method that displays the ship's name and the year it was built.Disign a CruiseShip class that extends the Ship class. The CruiseShip class should have thefollowing members:• A field for the maximum number of passengers (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CruiseShipclass's toString method should display only the ship's name and the maximum number ofpassengers.Design a CargoShip class that extends the Ship class. The CargoShip class should have thefollowing members:• A field for the cargo capacity in tonnage (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CargoShipclass's…- Simple factory is not considered a design pattern because it does not decouple the client from concrete classes Select one: True False 2- structural patterns provide guidance on the way in which classes interact to distribute responsibility Select one: True False 3- The Simple factory is used when you want to limit the instantiation of classes to one implementation Select one: True False 4- When a class A is composing a reference to another class B, then we say that class A has-a class B relationship Select one: True False
