Design a ‘book’ class with title, author, publisher, price and author’s royalty as instance variables. Provide getter and setter properties for all variables. Also define a method royalty() to calculate royalty amount author can expect to receive the following royalties:10% of the retail price on the first 500 copies; 12.5% for the next 1,000 copies sold, then 15% for all further copies sold. Then design a new ‘ebook’ class inherited from ‘book’ class. Add ebook format (EPUB, PDF, MOBI etc) as additional instance variable in inherited class. Override royalty() method to deduct GST @12% on ebooks

Write a SelfPayKiosk class to support basic operations such as scan item, cancel transaction, checkout, and make payment. SelfPayKiosk.java is provided with method stubs. . Step 0. Declare private fields for number of customers served (int), total sales (double), and current amount due (double). Note the provided final variable for sales tax of 7%. Step 1 . Complete the constructor to initialize all private fields to zero. Complete the accessor methods to return the number of customers served, total sales, and current amount due. Step 2 . Complete the scanItem() method. Increase the amount due by parameter price. Do not update amount due if parameter price is negative. Step 3. Complete the checkOut() method. Multiply amount due by SALES_TAX and add to amount due. Step 4. Complete the makePayment() method. If parameter payment is enough to pay the amount due, increase total sales by amount due, increment number of customers served, and reset amount due to zero in preparation for…
(1) Add an __init__ method to the Widget class below. Each object of type Widget should have an instance variable called name and an instance variable called cost that represents a cost in dollars; those values are passed in when an object of type Widget is initialized. (2) Add a method to class Widget called is_cheap that returns True if the cost is less than $10, and False otherwise. (3) Add proper doctrings along with two examples for each method. You may use the Sample Usage code given below in your work.
Consider the above scenario, where Billing class has composition relationship with Doctor having private instance variables (docName, docID and docFee) and a public getDocID() method, Patient having private instance variables (pName, pID, pDisease), Medicine having private instance variables (medID, medName, medQty, medPrice), and MedicalTest having private instance variables (testID, testName, testPrice). In addition, each class shall have toString method to display its object state. Also define getDocInfo method in Billing class that shall return the doctor. Implement getPaymentAmount() method in Billing class that shall return the total billing amount that includes doctor fee, medicine cost and medical tests fee. Considering the above scenario, write code that shall perform the following in the driver/test class: Get an amount from user. Traverse the ArrayList<Billing> using enhanced for loop. Print the billing details of those bills having total billing amount greater or…
Note: Write a Java program given below Question # 1: Define a class for Students with field name, age, marks. Define getter and setter for all the fields. In the setter method, if age is less than 0, print that Age is less than zero. Similarly, if marks is less than zero or greater than 100, print in correct marks and don’t assign marks to member variable. In the Test class, create student’s object and assign the marks and age to appropriate values. Try assigning incorrect values to check if getter and setter methods work as expected.
Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the reference of any child class object. That…
Extend the ItemToPurchase class per the following specifications: Private fields string itemDescription - Initialized in default constructor to "none" Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0) Public member methods setDescription() mutator & getDescription() accessor printItemCost() - Outputs the item name followed by the quantity, price, and subtotal printItemDescription() - Outputs the item name and description Ex. of printItemCost() output: Bottled Water 10 @ $1 = $10 Ex. of printItemDescription() output: Bottled Water: Deer Park, 12 oz.
Write a class encapsulating the concept of the weather forecast, assuming that it has the following attributes: the temperature and the sky conditions (e.g. sunny, snowy, cloudy, rainy, etc.). Include a default constructor, an overloaded constructor, accessors and mutators, and the methods, toString() and equals(). Temperature, in Fahrenheit, should be between -50 and +150; the default value is 70, if needed. The default sky condition is sunny. In Addition, include a method that converts Fahrenheit to Celsius. Celsius temperature = (Fahrenheit temperature – 32) * 5/9. Also include a boolean method that checks whether the weather attributes are consistent (there are two cases where they are not consistent: when the temperature is below 32 and it is not snowy, and when the temperature is above 100 and it is not sunny). Write a client class to test all the methods in your class.
package1 and package2 are instances of the Box class. Attributes length, width, and height of both package1 and package2 are read from input. Then, scaling_factor1 and scaling_factor2 are read from input. In the Box class, define instance method scale_measurements() with self and one integer as parameters to: Assign attribute length with length's current value multiplied by the integer parameter. Assign attribute width with width's current value multiplied by the integer parameter. Assign attribute height with height's current value multiplied by the integer parameter.
In Java, Create a class Rectangle with double attributes length and width. The default constructor should set these attributes to 1. Provide methods that calculate the rectangle's perimeter and area, as well as accessors and mutators for both data fields. The mutator methods for length and width should verify that the number being passed in is larger than 0.0 and less than 20.0 -- if it doesn't fit those criteria, the value of the field should not be changed.Write a Driver class in the same file to test your Rectangle class. It should prompt the user to enter a length and width of a rectangle, and then print out the area and perimeter of the rectangle. (Use the mutators to set the length and width of the rectangle, not the constructor.)
Create a PhoneListing class that uses the Name class for one of its instance variables. Remember the instance data in the Name class is private to the class and must be accessed through its methods.Add additional instance variables to the PhoneListing class for the phone number. The phone number should be broken down into three parts, area code, city code, and local code.Create all appropriate methods for the new class, including the following three methods: equals(PhoneListing):boolean, an equality of state method that returns true if the objects contain the same name and phone number. compareTo(PhoneListing):int, a comparison method that returns -1 if the calling PhoneListing object should precede the argument PhoneListing object, 1 if the calling PhoneListing object should come after the argument PhoneListing object, and a 0 if they are equal. Use last, first, middle, phone number as the ordering values. example:Adams, Alex, Henry, (609)473-2101 Adams, George, Henry, (509)373-1101…
