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.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
- Draw the UML diagram for the class and then implement the class.

- Create an application for Ninas Cookie Emporium named CookieDemo that declares and demonstrates objects of the CookieOrder class and its descendants. The CookieOrder class includes auto-implemented properties for an order number, recipients name, and cookie type (for example, chocolate chip), and fields for number of dozens ordered and price. When the field value for number of dozens ordered is set, the price field is set as $15 per dozen for the first two dozen and $13 per dozen for each dozen over two. Create a child class named Special Cookieorder, which includes a field with a description as to why the order is special (for example, gluten-free). Override the method that sets a CookieOrders price as described in part a, but also to include special handling, which is SIO for orders up to $40 and $8 for higher-priced orders. Create an application named CookieDem02 that demonstrates using several Special CookieOrder objects.ShoppingCart.java - Class definition ShoppingCartManager.java - Contains main() method Build the ShoppingCart class with the following specifications. Private fields String customerName - Initialized in default constructor to "none" String currentDate - Initialized in default constructor to "January 1, 2016" ArrayList cartItems Default constructor Parameterized constructor which takes the customer name and date as parameters Public member methods getCustomerName() accessor getDate() accessor addItem() Adds an item to cartItems array. Has a parameter of type ItemToPurchase. Does not return anything. removeItem() Removes item from cartItems array. Has a string (an item's name) parameter. Does not return anything. If item name cannot be found, output a message: Item not found in cart. Nothing removed. modifyItem() Modifies an item's description, price, and/or quantity. Has a parameter of type ItemToPurchase. Does not return anything. If item can be found (by name) in cart,…Create a class Car with parameters companyName, color, maxSpeed (Not more than 150) andcategory. Use appropriate data types and access specifiers. Use default constructor to create objectsof cars. Write methods to set and get the values of parameters of car. Write methods to find categoryof car and to display the complete details of car along with category. Create another class TestCarwhich creates array of n number of cars, uses appropriate set methods to set the values of parametersof every car. Display the details of each car. (If max speed is between 120 and 150 then category is“High speed” otherwise “Normal”) (JAVA)
- Define the MyRectangle2D class that contains: Two double data fields named x and y that specify the center of the rectangle with getter and setter methods. (Assume the rectangle sides are parallel to x- or y-axis.) The data fields width and height with getter and setter methods. A no-arg Constructor that creates a default rectangle with (0, 0) for (x, y) and 1 for both width and height. A Constructor that creates a rectangle with the specified x, y, width, and height. A method getArea() that returns the area of the rectangle. A method getPerimeter() that returns the perimeter of the rectangle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this rectangle (see Figure 10.24a ). A method contains(MyRectangle2D r) that returns true if the specified rectangle is inside this rectangle (see Figure 10.24b ). A method overlaps(MyRectangle2D r) that returns true if the specified rectangle overlaps with this rectangle (see Figure 10.24c) NOTE:…FootballTeam ClassDefine a class in the FootballTeam java file that will represent a football team as follows: ● The class has the following three fields which cannot be accessed outside of the class. • name of the team (teamName)• number of wins (numOfWins)• number of losses (numOfLosses)● Write a constructor that accepts the name of the team (n), the number of wins (w), and the number of losses (l) as arguments and sets the class properties to those values. ● Write methods that return the name of the team (getTeamName), the number of wins (getNumOfWins), and the number of losses (getNumOfLosses). ● Next, write a method to increase the numbers of wins by 1 (increaseWins) and another method to increase the number of losses by one (increaseLosses). ● Write a method that returns true when a team has a “good record,” meaning the team has more wins than losses(getRecord).● Write a driver program in the FootballTeamDemo class. ○ In the main method, construct a FootballTeam named…PPM (Portable Pixmap) use three integers to represent a pixel – this means we can have images with RGB colors. You will create a Pixel class in C++ which has three attributes: red: int green: int blue: int You will create a default constructor that initializes those values to 255, and an overloaded constructor that takes user input to assign the values. The class will also have the following functions: changeRGB (): Takes in three integers to update the red, green, and blue attributes. Returns nothing. printRGB (): Takes in nothing. Prints the red, green, and blue attributes in order with a single space in-between each value. Returns nothing. You will then recreate the art program from Assignment 5 with the following changes: Instead of a 2D array of integers, you will create a 2D array of Pixel object. Don’t be scared! This is similar to creating a 2D array of strings. You will prompt for three color values instead of one – red, green, and blue. These must be stored in a Pixel…
- Create an AlienType class. Include at least three protected data members of your choice, such as the number of eyes the Alien has. Include a constructor that requires a value for each data field and an output method that returns a String containing a complete description of the Alien. Save the file as AlienType.cpp. Create two classes—MartianType and JupiterianType—that descend from Alien. Supply each with a constructor that sets the Alien data fields with values you choose. For example, you can decide that a Martian has four eyes but a Jupiterian has only two. Save the files as MartianType.cpp and JupiterianType.cpp.Create an application that instantiates one Martian and one Jupiterian. Call the output method with each object and display the results. Save the application as CreateAliens.cpp.10. Please do in java code DJ classDesign, implement and test a DJ class. A DJ object has a name - djName and an isHired attribute (boolean). Also, a DJ object has 3 musicTypes. These are references to the Music class, where the musicType is declared. In Stage 2 you will be required to declare these 3 instance variables as 1 array.A DJ object can return the value of each of its attributes, and change the value of each of its attributes. It can also display itself in the form:Kongapa, Play List: Disco, Rap, Heavy Metal is hiredImpressions, Play List: House, Hip Hop, Jazz is availableWrite Rectangle class to represent a rectangle. The class contains:a. Two double data fields named width and height that specify the width and height ofthe rectangle. The default values are 1 for both width and height.b. A no-arg constructor that creates a default rectangle.c. A constructor that creates a rectangle with the specified width and height.d. A method named getArea() that returns the area of this rectangle.e. A method named getPerimeter() that returns the perimeter. in Java
