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:
Write an C#application for Nina’s Cookie Emporium named CookieDemo that declares and demonstrates objects of the CookieOrder class and its descendants. The CookieOrder class includes the following auto-implemented properties:
- OrderNum - The order number
- Name - The recipient’s name
- CookieType - The cookie type (for example, chocolate chip)
The class should also include fields for number of dozens ordered and price (named Dozens 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.
Next, create a child class named SpecialCookieOrder, 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 the step above, but also to include special handling, which is $10 for orders up to $40 and $8 for higher-priced orders.

- Write a C# application AutomobileDemo that prompts a user for data for eight Automobile objects. The Automobile class includes the following auto-implemented properties: IdNumber - The ID number (an int) Make - The make (a string) Year - The year (an int) Price - The price (a double) Override the ToString() method to return all the details for an Automobile. During data entry, re-prompt the user if any ID number is a duplicate. Sort the objects in ID number order, and display all their data as well as a total of all their prices. For example if, the output should be in the following format (only two automobiles shown): Automobile 1 2017 honda Price is $30,000.00 Automobile 45 2016 Toyota Price is $20,000.00 Total for all Automobiles is $50,000.00. using System; using static System.Console; using System.Globalization; class AutomobileDemo { static void Main() { // Your code here } }JAVA PROGRAM For this program, you are tasked to implement the Beverage class which has the following private properties: name - a string value volume - this is an integer number which represents its current remaining volume in mL isChilled - this is a boolean field which is set to true if the drink is chilled It should have the following methods: isEmpty() - returns true if the volume is already 0 {toString() - returns the details of the object in the following format: {name} ({volume}mL) {"is still chilled" | "is not chilled anymore"}.Example returned strings: Beer (249mL) is still chilled Water (500mL) is not chilled anymore A constructor method with the following signature: public Beverage(name, volume, isChilled) Getter methods for all the 3 properties. Then, create two final subclasses that inherit from this Beverage class. The first one is the Water class which has the additional private property, type, which is a String and can only be either "Purified", "Regular",…Write 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.
- 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).Write 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.In C#, Create a program named ConferencesDemo for a hotel that hosts business conferences. Allows a user to enter data about five Conference objects and then displays them in order of attendance from smallest to largest. The Conference class contains fields for the following: group - The group name (as a string) date - The starting date (as a string) attendees - The number of attendees (as an int) Include properties for each field. Also, include an IComparable.CompareTo() method so that Conference objects can be sorted in order from least to greatest attendees.

Please have this in the code], at least one overloaded constructor, all set/get methods, and a toString function For the Home class, also provide method(s) to determine if a home is large and if it has more than one bathroom For the Address class, provide method(s) to determine if an address is in a given city, state, or zip code Write a test program that adequately tests all the classes and all their functions You can hard code your test values in main where you…Write the application AutomobileDemo that prompts a user for data for eight Automobile objects in C# language The Automobile class includes the following auto-implemented properties: IdNumber - The ID number (an int) Make - The make (a string) Year - The year (an int) Price - The price (a double) Override the ToString() method to return all the details for an Automobile. During data entry, re-prompt the user if any ID number is a duplicate. Sort the objects in ID number order, and display all their data as well as a total of all their prices. For example if, the output should be in the following format (only two automobiles shown): Automobile 1 2017 honda Price is $30,000.00 Automobile 45 2016 Toyota Price is $20,000.00 Total for all Automobiles is $50,000.00
