OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

- 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…The attributes field of objects is a place where data may be saved. The class is solely responsible for its own properties.Describe how you can use an interface as an alternative to a class to specify the type for a parameter.
- Practice with writing a program that contains three classes: Ship CruiseShip CargoShip Classes Design a Ship class with 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 that accepts two arguments for the two fields, and appropriate accessors and mutators A toString method that returns a string with the ship’s name and the year it was built Design a CruiseShip class that extends the Ship class. The CruiseShip class should have the following members: A field for the maximum number of passengers (an int) A constructor that accepts three arguments for the three fields and appropriate accessors and mutators A toString method that overrides the toString method in the base class. The CruiseShip class’s toString method should return a string with only the ship’s name and the maximum number of passengers. Design a CargoShip class that extends the Ship class. The CargoShip class should have the…Problem: Course information System Super Class Attributes Methods : Student Studentid, StudentName, Address, Level Set the student details using constructor Display the Student details Sub class : Course Attributes Methods Coures1, Course2, Credit1, Credit 2, Mark1, Mark2 Set the course details using constructor Calculate the total number of credits Calculate the total number of marks Display the course details Driver Class : Display the student details and course details.

- 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.Data may be stored in the attributes field of objects. The class's characteristics are the class 's own.?class Widget: """A class representing a simple Widget === Instance Attributes (the attributes of this class and their types) === name: the name of this Widget (str) cost: the cost of this Widget (int); cost >= 0 === Sample Usage (to help you understand how this class would be used) === >>> my_widget = Widget('Puzzle', 15) >>> my_widget.name 'Puzzle' >>> my_widget.cost 15 >>> my_widget.is_cheap() False >>> your_widget = Widget("Rubik's Cube", 6) >>> your_widget.name "Rubik's Cube" >>> your_widget.cost 6 >>> your_widget.is_cheap() True """ # Add your methods here if __name__ == '__main__': import doctest # Uncomment the line below if you prefer to test your examples with doctest # doctest.testmod()
- CLASS NAME List the instance variables in the constructor. List the methods in the class. - indicates private CLASS NAME List the instance variables in the constructor. List the methods in the class. The second row of the UML diagram lists the instance variables in the constructor. For example -name: string o o name is the variable name o string is the data type of name + indicates public o getName is the method name o o string is the return data type Java.util. The third row of the diagram lists the methods in the class. For example, +getName(): string empty parenthesie indicate nothing is sent to the method.You must provide protection for class fields against accidental modification.Part I - Design a class named Business that contains: JavaDoc comments on the entire class definition only JavaDoc at the top of the class application only A String attribute named name for the Business name A String attribute named symbol for the Business’s stock symbol A double attribute named lastPrice that stores the stock price one month ago A double attribute named currentPrice that stores the stock price for the current time A default constructor An overloaded constructor that creates a Business with a specified Business stock symbol and name An overloaded constructor with all attributes Accessors and mutators for each attribute A copy Constructor An Equals Method A toString() method to display current state of the object, formatted! Create a BusinessDriver application. You will have at least 4 methods in this application main() – setBusinessData() - this reads the data from the file (call the file businessData.txt) displayBusinessData() - this displays the data to…
