The Rockford Daily Clarion wants you to design a class named Issue. Fields include the issue number, the total number of advertisements sold in each issue, and total advertising revenue. Include get and set statements for each field. Include a static method that displays the newspaper's motto (Everything you need to know) Include three overloaded contractors as follows. A default constructor that sets the issue number to 1 and the other fields to 0. A constructor that allows you to pass values for all three fields. A constructor that allows you to pass an issue number and a number of advertisements sold but sets the advertising revenue at 50$ per ad.

Create a UML Diagram of a class named Investment with fields called principal and interest. It also contains methods named value_after that returns the value of the investment after n years. The formula for this is p(1+i)ⁿ, where p is the principal, and i is the interest rate.

A main method can be placed inside a class definition. O True O False

For your homework assignment, build a simple application for use by a local retail store. Your program should have the following classes: Item: Represents an item a customer might buy at the store. It should have two attributes: a String for the item description and a float for the price. This class should also override the __str__ method in a nicely formatted way. Customer: Represents a customer at the store. It should have three attributes: a String for the customer's name, a Boolean for the customer's preferred status, and a list of 5 indexes to hold Item objects. Include the following methods: make_purchase: accepts a String and a double as parameters to represent the name and price of an item this customer is purchasing. Create a new Item object with this info and append it to the internal list. If the customer is a preferred customer based on the Boolean attribute's value, take 10% off the total sale price. __str__: Override this method to print the customer's name and every…

in C#, Visual Basic Create a Car class that has at least the following properties:• Year• Make• Price• Passengers-holds the number of seat belts available in the car (presumably how many passengers the car can hold). This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car. The Get Paint Color() and Upgrade Costs() functions needs to be called for each object and data for all…

Can someone please help me with the main code? The code for the business class is down below. Part I - Design a class named Business that contains: A String attribute named name for the Business name A String attribute named symbol for the Business’s stock symbol A double attribute named lastPrice that stores the stock price one month ago A double attribute named currentPrice that stores the stock price for the current time A default constructor An overloaded constructor that creates a Business with a specified Business stock symbol and name An overloaded constructor with all attributes Accessors and mutators for each attribute A copy Constructor    An Equals Method    A toString() method to display current state of the object, formatted! Part 2- Create a BusinessDriver application. You will have at least 4 methods in this application main() – setBusinessData() - this reads the data from the file (call the file businessData.txt) displayBusinessData() - this displays the data to the…

Assume method testQuestion() is a method in the Purchase class. Assume the Purchase class has a constructor that has parameters of name, groupCount, groupPrice, and numberBought. public Purchase testQuestion(Purchase p1, int newX) { newX = 20; this.setName("green beans"); p1.setName("corn"); Purchase p2 = new Purchase("broccoli", 5, 4.50, 10); return p2; } Referring to the above method, list the output that would be printed by Sysyem.out.println() when the following PurchaseDemo2 is executed. public class PurchaseDemo2 { public static void main(String[] args) { Purchase tomsPurchase = new Purchase("squash",4,3.50,6 ); Purchase jillsPurchase = new Purchase("carrot",8,1.99,4 ); Purchase billsPurchase;…

Design a class named octopus that holds attributes for an octopus named weight and color. Include methods to set and get each of these attributes. Create the class diagram and write the class pseudocode that defines the class. Create a small program that declares two octopus objects and set the octopus's name weight and color attributes the program must also output each octopus's name weight and color after they are set. Please write out the pseudocode. I have a hard time with this.
