Homework Assignment Chapter 10b Create a new Java Project named Chap10b Create a class named Vehicle that acts as a superclass for vehicle types. The Vehicle class contains private data fields for the number of wheels and the average number of miles per gallon. The Vehicle class contains getters and sette for the data fields. The Vehicle class also contains a constructor receiving intege parameters for the number of wheels and average miles per gallons, and a display() method that prints the required output (use get methods). Create two subclasses, Car and MotorCycle, that each extend the Vehicle class. Each subclass contains a constructor that accepts the miles-per-gallon value as a argument and forces the number of wheels to the appropriate value-2 for a MotorCycle and 4 for a Car. Use the superclass constructor to set the wheels and mpg data fields (use the super keyword). Write a UseVehicle class to instantiate one object of each subclass and calls the displa method to print the object's values. Save the files as Vehicle.java, Car.java, MotorCycle.java, and UseVehicle.java For reference, see page 490-491. Zip the folder Chap10b and upload. Make sure your code has the following comments at the beginning of each file with the appropriate information: //Filename //Author //Date Console Output: LWhoolc: 4 Mng: 20

Part A Create a FitnessTracker class that includes three data fields for a fitness activity: a String for the name of the activity as activity, an int for the number of minutes spent participating as minutes, and a LocalDate for the date as date. Create a default constructor that automatically sets the activity to running, the minutes to 0, and the date to January 1 of the current year. Overload the constructor so it receives parameters for each of the fields and assigns them appropriately. Includes methods to get each data field. Part B Create an application that instantiates two FitnessTracker objects. Prompt the user for values for one object, and pass those values to the three constructor parameters. Retain the default constructor values for the other object. Display the values for each object. An example of the program is shown below: Enter activity >> swimming Enter minutes spent swimming >> 90 Enter month >> 2 Enter day >> 24 Enter year >> 2021...

C# i need to Create an application named TurningDemo that creates instances of four classes: Page, Corner, Pancake, and Leaf. Create an interface named ITurnable that contains a single method named Turn(). The classes named Page, Corner, Pancake, and Leaf implement ITurnable. Create each class’s Turn() method to display an appropriate message. For example: The Page’s Turn() method should display You turn a page in a book.The Corner’s Turn() method should display You turn corners to go around the block.The Pancake's Turn() method should display You turn a pancake when it's done on one side.The Leaf's Turn() method should display A leaf turns colors in the fall i keep getting errors C# i need to Create an application named TurningDemo that creates instances of four classes: Page, Corner, Pancake, and Leaf.

1. RetailItem Class Write a class named Retailltem that holds data about an item in a retail store. The class should have the following fields: • description. It is a String object that holds a brief description of the item. • unitsOnHand. It is an int variable that holds the number of units currently in inventory. • price. It is a double that holds the item's retail price. Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three RetailItem objects and stores the following data in them. Units On Hold Description Designer Jeans Jacket Price 40 34.95 12 59.95 Shirt 20 24.95

Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks: Bonds: Purchase date (Date) Purchase date (Date) Purchase price (double)...

Exercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the account
