- Write a shoe class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "nikes, adidas", "puma") price (e.g., 100, 200,60) Include only one constructor. It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230(1) Extend the ItemToPurchase class to contain a new attribute. item_description (string) - Set to "none" in default constructor Implement the following method for the ItemToPurchase class. print_item_description() - Prints item_description attribute for an ItemToPurchase object. Has an ItemToPurchase parameter. Ex. of print_item_description() output: Bottled Water: Deer Park, 12 oz. (2) Build the ShoppingCart class with the following data attributes and related methods. Note: Some can be method stubs (empty methods) initially, to be completed in later steps. Parameterized constructor which takes the customer name and date as parameters Attributes customer_name (string) - Initialized in default constructor to "none" current_date (string) - Initialized in default constructor to "January 1, 2016" cart_items (list) Methods add_item() Adds an item to cart_items list. Has parameter ItemToPurchase. Does not return anything. remove_item() Removes item from cart_items list.…Design and implement a class called Car that contains instance data that represents the company, price, model, and year of the car. Define the Car constructor to initialize these values. Include getter and setter methods for all instance data, and a toString method that returns a one-line description of the car. Create a driver class called CarTest, whose main method instantiates array of Car objects and write the following methods: 1) Methods that receives an array of cars and a string called co and returns an array that contains cars whose company equal to co. 2) A Method called getTopByCompany that receives an array of Cars and then returns an array of cars containing the cars that have the highest price compared with cars from the same company.
- Design and implement a class called Car that contains instance data that represents the make, model, and year of the car (as a String, String and int value respectively). Define the Car constructor to initialize these values (in that order). Include getter and setter methods for all instance data, and a toString method that returns a one-line description of the car of the form make-model (year)for example:Ford-Thunderbird (1955)Create a class Course to describe a course according to the following requirements: A course has three attributes: courseName, courseCode, fees. Create a constructor without parameters to initialize all the instance variables to default values (0 for numbers and "" for a string). Create a constructor to initialize all the attributes to specific values. Add all setter and getter methods Create a tester class with the main method. The tester class must be named using your first and last In this class performs the following: Create a course object c1 using the default constructor. Create a course object c2 with the following information: courseName =” object oriented programing”, courseCode = “CS230” , fees = a value from your choice. Change the course fees of c2 to your age. Print the course information of c2 using getter methods I attached Typical run of the program1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…
- Deeper Class Design - the Square Class In this section, your job will be to write a new class that will adhere to the methods and data outlined in the “members” section below (said another way, your classes will implement a specific set of functions (called an interface) that we’ll describe contractually, ahead of time). These classes will all be shapes, with actions (methods) that are appropriate to shape objects, such as “getArea()”, or “draw()”. First we build a Square class that contains the following data and methods listed below, and then later, we will copy it to quickly make a Circle class. Note: when considering each data item below, think about what type of data would best represent the concept we’re trying to model in our software. For example, all shapes will have a coordinate pair indicating their location in a Cartesian coordinate system. This x and y pair may be modeled as ints or floats, and you might choose between the two depending on what the client application will…Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.The class "Car" has the following attributes: plate (String), mark (String), model (String), year (int), km (int).Write a constructor method for the "Car" class that takes values as parameters for all these attributes.
- B - RobotFriend Create a RobotFriend class. RobotFriend is a new toy just on the market. Copy the starter class and the tester from Codecheck. A RobotFriend has a name and replies to various commands Provide a constructor that takes the name of the RobotFriend as a parameter. Remember that a constructor has the same name as the class. What does the class need to remember? That is the instance variable. Provide the following methods: public String getName () gets the name of this RobotFriend • public void setName (String newName) sets a new name for this RobotFriend • public String whatDoYouNeed () returns a string consisting of name + needs a battery charge" where name is the name of this RobotFriend (which was supplied in the constructor) public String doCommand (String whatToDo) returns a string consisting of "Your friend " + name + does not + whatToDo where name is the name of this RobotFriend and whatToDo is the parameterDefine the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. A data field radius with a get method. A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. A constructor that creates a circle with the specified x, y, and radius. A method getArea() that returns the area of the circle. A method getPerimeter() that returns the perimeter of the circle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure 10.14(a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure 10.14(b). A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. Figure (a) A point is inside the circle. (b) A circle is inside another circle. (c) A circle overlaps another circle. Draw the UML diagram for the class.…Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…
