- Create an application for Nina’s 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, recipient’s 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 CookieOrder’s 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.

- a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).arrow_forwardWrite a FractionDemo program as a Console Application that instantiates several Fraction objects and demonstrates that their methods work correctly.

- In Kotlin, Write a Circle data class, with a radius as a parameter to the constructor, a custom-coded property for the area, and a sizeRatio() function that takes a reference to another Circle and returns the ratio of the radius of the instance circle (the one you call the function on) to the other circle . Use math.pow and math.PI. Write a main() that creates a circle, prints it (which will print it's automatically generated toString()), prints its radius, creates another circle, and shows the size ratio of the two.arrow_forwardWrite a program named DemoJobs for Harolds Home Services. The program should instantiate several Job objects and demonstrate their methods. The Job class contains four data fields—description (for example, wash windows), time in hours to complete (for example, 3.5), per-hour rate charged (for example, $25.00), and total fee (hourly rate times hours). Include properties to get and set each field except the total fee—that field will be read-only, and its value is calculated each time either the hourly fee or the number of hours is set. Overload the + operator so that two Jobs can be added. The sum of two Jobs is a new Job containing the descriptions of both original Jobs (joined by and), the sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. Harold has realized that his method for computing the fee for combined jobs is not fair. For example, consider the following: His fee for painting a house is $100 per hour. If a job takes 10 hours, he earns $1000. His fee for dog walking is $10 per hour. If a job takes 1 hour, he earns $10. If he combines the two jobs and works a total of 11 hours, he earns only the average rate of $55 per hour, or $605. Devise an improved, weighted method for calculating Harolds fees for combined Jobs and include it in the overloaded operator+() method. Write a program named DemoJobs2 that demonstrates all the methods in the class work correctly.arrow_forwardWrite a program named SalespersonDemo that instantiates objects using classes named Real EstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each objects data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salespersons full name—the first and last names separated by a space. Then perform the following Create two child classes of Salesperson: Real EstateSalesperson and Girl Scout. The Real EstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are initialized to 0), and a commission rate field required by the class constructor. The Girl Scout class includes a field to hold the number of boxes of cookies sold, which is initialized to 0. Include properties for every field. Create an interface named ISell able that contains two methods: SalesSpeech() and MakeSale(). In each Real EstateSalesperson and Girl Scout class, implement SalesSpeech() to display an appropriate one- or two-sentence sales speech that the objects of the class could use. In the Real Estatesalesperson class, implement the MakeSale() method to accept an integer dollar value for a house, add the value to the Real EstateSalespersons total value sold, and compute the total commission earned. In the Girl Scout class, implement the MakeSale() method to accept an integer representing the number of boxes of cookies sold and add it to the total field.arrow_forward

The Chicken class must:• Define three fields called exactly name, pricePerKilo and inStock. The name field must be of type String, the pricePerKilo must be of type int (representing the cost per kilo in pence) and the inStock field must be of type boolean.• Initialise the three fields via a constructor that takes exactly two parameters. The first parameter must be of type String and the second parameter must be of type int. The first parameter must initialise the name field and the second must initialise the pricePerKilo field. The constructor must set the inStock field to true for all Chicken objects. There must be no parameter to the constructor for the inStock field.• Define getters for all three fields using the standard getter naming convention. In particular, note that the getter for the inStock field must be called getInStock rather than isInStock.• Define setters for the pricePerKilo and inStock fields using the standard…arrow_forwardJAVA CODE For this program, you are tasked to create a class called Person which will have the following private properties: name - a string which holds the name of the person. age - an integer which holds the age of the person. gender - a character which holds the gender of the person. This could either be 'M' or 'F' Then, for this class, you need to create its getters and setters for all of its properties and its toString() method which simply returns its name, age, and gender in the format, name - age - gender. An example returned value from its toString() method is "Luce - 25 - M". Also implement its constructor with the following signature: public Person(String name, int age, char gender) Additionally, you need to implement its isMinor() method which basically returns true if its age is lesser than 18 and false otherwise. After creating the class Person, create the class Father which inherits from the Person class. This class will have a constructor with the following…arrow_forward
- You are designing an application to rate your professors.a. Professors have the following properties: first name, last name, universityname, subject, and ratings for overall quality (1.0-5.0) and level of difficulty(1.0-5.0).
