design a class named Stock that contains: ▪ A string data field named symbol for the stock's symbol. ▪ A string data field named name for the stock's name. ▪ A double data field named price for the previous day. ▪ A double data field named currentPrice that stores the stock price for the current time. ▪ A constructor that creates a stock with the specified symbol and name. ▪ A method named getChange Percent () that returns the percentage changed from previous ClosingPrice to currentPrice. Draw the UML diagram for the class then implement the class. Write a test program that creates a Stock object with the stock symbol ORCL, the name Oracle Corporation, and the previous closing price of 34.5. Set a new current price to 34.35 and display the price-change percentage. previousClosingPrice that stores the stock

Design a Book class that holds the title, author’s name, and price of the book. Books’s constructor should initialize all of these data members except the price which is set to 500/-. Create a display method that displays all fields. All Books are priced at 500/- unless they are PopularBooks. The PopularBooks subclass replaces the Bookprice and sets each Book’s price to 50,000/- through PopularBooks construcor. Override the display method to display all fields. Write a Main () method that declares an array of five Book objects. Ask the user to enter the title and author for each of the 5 Books. Consider the Book to be a PopularBook if the author is one of the following: Khaled Hosseini, Oscar Wilde, or Rembrandt. Display the five Books’ details. c sharp
Car Class Project The car classwill havethe following attributes: •year: an integer that holds the car's model year •model: a string that holds the make of the car •make: a string that holds the model of the car •speed: an integer that holds the car's current speed Your class should contain thefollowing: A docstring that briefly describes the class and lists the attributes. The docstring will serve as the documentation for your class. •A constructor (__init__ method) that takes the car's year model and make as optional arguments. The constructor will set the value of the speed attribute to 0.•An __str__ method that returns the car's year model and makein a string. •To test your class, create acar object and use the print function to verify that the constructor and __str__ methodsare working correctly. •An accessor method which returns the value stored in the speed instance variable. Call this method getSpeed(). •A modifier method called accelerate() which adds 5 to the speed variable…

1. Create a class as described below: Class Name: Room Fields: standard room fee amenities total cost Constructors:A default constructor to initialize the fields. The standard room fee field should be set to $200 and the amenities field to zero. Another constructor with one argument. It should assign this value to the standard room fee and the amenities field to the default value of $75. Methods: getStandardFee() - This methods returns the standard room fee field value. getAmenities() - This method returns the amenities field value. getTotalCost() - This method returns the total cost field value. calcTotalCost() - This method calculated the total cost for an instance of the class setStandard Fee() - This method has one argument representing the standard room fee. setAmenities() - This method has one argument representing the amenities for the room.
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…
Design a class named Fan to represent a fan. The class contains: VideoNote The Fan class ▪ Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denote the fan speed. ▪ A private int data field named speed that specifies the speed of the fan (the default is SLOW). ▪ A private boolean data field named on that specifies whether the fan is on (the default is false). ▪ A private double data field named radius that specifies the radius of the fan (the default is 5). ▪ A string data field named color that specifies the color of the fan (the default is blue). ▪ The accessor and mutator methods for all four data fields. ▪ A no-arg constructor that creates a default fan. ▪ A method named toString() that returns a string description for the fan. If the fan is on, the method returns the fan speed, color, and radius in one combined string. If the fan is not on, the method returns the fan color and radius along with the string "fan is off" in one combined string. Draw the UML…

Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc.  Then create characteristics (breed, age, size, color) can form a data member for your object. Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.
Part A Create a class named Apartment that holds an apartment number as aptNumber, number of bedrooms as bedrooms, number of baths as baths, and rent amount as rent. Create a default constructor that accepts no arguments and an overloaded constructor that accepts values for each data field. Also create a get method for each field. Part B Write an application called TestApartments that creates at least five Apartment objects. Then prompt a user to enter a minimum number of bedrooms required, a minimum number of baths required, and a maximum rent the user is willing to pay. Display data for all the Apartment objects that meet the user’s criteria or an appropriate message if no such apartments are available. An example of the program is shown below: Enter minimum number of bedrooms needed >> 2 Enter minimum number of bathrooms needed >> 1.5 Enter maximum rent willing to pay >> 1200 Apartments meeting criteria of at least 2 bedrooms, at least 1.5 baths, and no more than…
