Create an application for Ninas 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, recipients 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 CookieOrders 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.
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 fieldsâ€”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 feeâ€”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.

Write a Java class named PhoneRecord.java that performs the following functions: The class should contain the following data attributes and methods: private String name - The customer's name private String number - The customer's phone number public PhoneRecord(String personName, String phoneNumber) - Constructor get/set Methods - For each data attribute public String toString( ) - Special method to be used when printing a phoneRecord object Thank you so much for your help. Trying to write this class has really been stumping me.
Problem Description and Given Info For this assignment you are given the following Java source code files: IStack.java (This file is complete – make no changes to this file) MyStack.java (You must complete this file) Main.java (You may use this file to write code to test your MyStack) You must complete the public class named MyStack.java with fields and methods as defined below. Your MyStack.java will implement the IStack interface that is provided in the IStack.java file. You must implement your MyStack class as either a linked list or an array list (refer to your MyArrayList and MyLinkedList work). Your MyStack must not be arbitrarily limited to any fixed size at run-time. UML UML CLass Diagram: MyStack Structure of the Fields While there are no required fields for your MyStack class, you will need to decide what fields to implement. This decision will be largely based on your choice to implement this MyStack as either an array list or a linked list. Structure of the Methods As…
Cake For this, we are editing the cake class You need to make 2 private properties with these names and datatypes: name (String), price (int) You need to make a constructor with no parameters and set the name to "Velvet" and price to 6 Both variables need set/get methods (setName, getName, setPrice, getPrice) Create a print method that prints the 2 properties. So, if the name was "Vanilla" and the price was 11, this would print:Vanilla 11 Main Skeleton public class Main { public static void main(String[] args) { Cake c = new Cake(); System.out.println(p.getName()); System.out.println(p.getPrice()); p.setName("Vanilla"); p.setPrice(11); p.print(); }}
Java question please Create a class called Account that has the following attributes: Account Client - AccountHolder Double - Balance Date - DateCreated Account() Account(Client AccountHolder, Double Balance) getAccountHolder() - Client setAccountHolder(Client) - void getBalance() - Double deposit(Double) - Double withdrawal(Double) - Double getDateCreated() - Date toString() - String compareTo(Account) - Integer equals(Account) - Double Notes: The account holder attribute will link to the Account class that you created in problem 6. Your constructor and overloaded constructor should set the date created to the current date. Your deposit method should add to the balance Your withdrawal method should remove from the balance, as long as there is enough money to withdrawal

JAVA 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…
Got stuck on this for my daily coding practice. I would like to understand it in Java. Given main(), complete the FoodItem class (in file FoodItem.java) with constructors to initialize each food item. The default constructor should initialize the name to "Water" and all other fields to 0.0. The second constructor should have four parameters (food name, grams of fat, grams of carbohydrates, and grams of protein) and should assign each private field with the appropriate parameter value. Ex: If the input is: Water the output is: Nutritional information per serving of Water: Fat: 0.00 g Carbohydrates: 0.00 g Protein: 0.00 g Number of calories for 1.00 serving(s): 0.00 Ex: If the input is: M&M's 10.0 34.0 2.0 3.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 3.0 is the number of servings, the output is: Nutritional information per serving of M&M's: Fat: 10.00 g Carbohydrates: 34.00 g Protein: 2.00…
Write program in C# WAP on Encapsulation to hide the type members with private access and display employee details. • Create new project, select console application from the template and name the project as "EmployeeDetails.cs". • Here type members are nothing but properties. • Create another class as Employee and write the properties for EmpId, EmpName and Salary. • Now, create an instance of the Employee class in the "EmployeeDetails" class and assign the values for EmpId,EmpName and Salary and print the values.
