(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.…
Challenge exercise The following object creation will result in the constructor of the Date class being called. Can you write the constructor’s header? new Date("March", 23, 1861) Try to give meaningful names to the parameters
Language is Java Write a Clothing class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "Doctor Who hoodie", "slacks") price (e.g., 19.99, 7) 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 Clothing 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 Clothing object whose color was blue, whose display name was work trousers, for a price of 27.99, you could use the getters to print something like this:These work trousers are blue and cost $27.99.Don't hardcode the print statement for full credit, you must use the getters
(Java) Question 5 Explain the answer step-by-step and include verbal explanation. Thank you! Write an interface as follows: The interface is named ServiceReminder It has one method named timeForService that has no parameters and returns a boolean variable. Now, update the below class so that is inherits from ServiceReminder Note that the next service date should be 90 days from the last service public abstract class Car { private double gasGauge; private double currMileage; private String color; private String make; private String model; private int daysLastService; public Car(String color, String make, String model, int daysLastService) { this.color = color; this.make = make; this.model = model; gasGauge = 0.0; currMileage = 0.0; this.daysLastService = daysLastService; } @Override public String toString() { return "Make: " + make + "\nModel: " + model + "\nColor: " + color…
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…
Design and implement a Restaurant class with at least three meaningful attributes and two methods. Implement a test program which creates at least two instances of the restaurant class and calls all the methods. Some possible attributes are name, numberOfTables, cuisine, numberOfReservations, capacity, etc. Some possible methods are make Reservation, checkAvailability, etc. Note the following: -All properties must be declared as private and you need accessor and mutator methods for each property. - You need to define at least one constructor. Documentation o Include header comments that include description of the program. o Include body comments o Consistent indentations o Consistent white line spaces Properties are declared as private o Accessor and mutator methods are created o At least one default constructor o At least two instances are created
Part (1) Define a class as follow: a. create a class called Student that has four instance variables - a (String) name, a (long) StudentID, a (String) College, and a (double) GPA. b. A constructor that takes student name, StudentID, College and GPA. The constructor sets the class variables to these values . c. Make the instance variable GPA private and provide a mutator method (set) and an accessor method (get) to access this variable. In set method if the GPA negative or grater than 4.00 print an invalid message and do not change the instance variable GPA. d. A method Student_Status () that check the GPA if it is less than 2, display the warning message, otherwise display Normal student. e. A method Print() that displays the name, StudentID, College and GPA of the student as shown below: Sample output: Enter the Student name: Ali Ahmed Enter the Student ID: 20180011 Enter the College: Information Technology Enter the GPA: 3.2 Normal student Name: Ali Ahmed Student ID: 20180011…

2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results. Statements and Expressions Value Returned Comment (blank if no value) StepTracker tr StepTracker(10000); Days with at least 10,000 steps are considered active. Assume that the parameter is positive. new tr.activeDays () ; No…
