Static & Not Final Field: Accessed by every object, Changing Non-Static & Final Field: Accessed by object itself, Non-Changing Static & Final: Accessed by every object, Non-Changing Non-Static & Not Final Field: Accessed by object itself, ChangingRead the following situation and decide how the variables should be defined. You have a class named HeartsPlayerA round of Hearts starts with every player having 13 cardsPlayers then choose 3 cards to “trade” with a player (1st you pass left, 2nd you pass right, 3rd you pass across, 4th you keep)Players then strategically play cards in order to have the lowest scoreAt the end of the round, points are cumulatively totaled for each player.If one player’s total is greater than 100, the game ends and the player with the lowest score wins. 1. How should the following data fields be defined (with respect to final and static)?(a) playerPosition (These have values of North, South, East, or West)(b) directionOfPassing(c) totalScore…
a - Create a FitnessTracker class that includes data fields for a fitness activity, the number of minutes spent participating, and the date. The class includes methods to get each field. In addition, 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. Save the file as FitnessTracker.java. Create an application that demonstrates each method works correctly, and save it as TestFitnessTracker.java. b - Create an additional overloaded constructor for the FitnessTracker class you created in Exercise 3a. This constructor receives parameters for each of the data fields and assigns them appropriately. Add any needed statements to the TestFitnessTracker application to ensure that the overloaded constructor works correctly, save it, and then test it. c - Modify the FitnessTracker class so that the default constructor calls the three-parameter constructor. Save the class as FitnessTracker2.java. Create an…
Create an Investment class that contains fields to hold the initial value of an investment, the current value, the profit (calculated as the difference between current value and initial value), and the percent profit (the profit divided by the initial value). Include a constructor with two arguments: initial, and current values and then calculate profit, and percent profit, and a display function that displays all fields. Create a House class that includes fields for street address and square feet, a constructor that requires values for both fields, and a display function. Create a HouseThatIsAnInvestment class that inherits from Investment and House. It includes a constructor (in order to pass arguments to its parent constructors) and a display function that calls the display functions of the parents. Write a main() function that declares a HouseThatIsAnInvestment and displays its values.
Write a class named RetailItem that holds data about an item in a retail store. The class should have the following properties:• Description—The Description property should hold a brief description of the item.• UnitsOnHand—The UnitsOnHand property should hold the number of units currently in inventory.• Price—The Price property should hold the item’s retail price. Write a constructor that accepts arguments for each property.The application should create an array of three RetailItem objects containing the following data: Description Units on Hand PriceItem 1 Jacket 12 59.95Item 2 Jeans 40 34.95Item 3 Shirt 20 24.95The application should have a loop that steps through the array, displaying each element’s properties.
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…

Create an application named SalesTransactiobDemo that declares several SalesTransaction objects and displays their values and their sum. Name - The salesperson name (as a string) sales Amount- The sales amount (as a double) commission- The commission (as a double) RATE- A readonly field that stores the commission rate (as a double). Define a getRate() avcessor method that returns the RATE Include 3 constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0 The third constructor accepts a name and sets all the other fields to 0
Question Create a class called Quadratic for performing arithmetic on and solving quadratic equations. A quadratic equation is an equation of the form ax2 + bx + c = 0 Where a !=0. Use double variables to represent the values of a, b, and c and provide a constructor that enables objects of this class to be initialized when they are created. Give default values of a = 1, b = 0, and c = 0. Create a char variable called variable to represent the variable used in the equation and give it a default value of x. The constructor should not allow the value of a to be 0. If 0 is given, assign 1 to a). Provide public member functions that perform the following tasks. add—adds two Quadratic equations by adding the corresponding values of a, b, and c. The function takes another object of type Quadratic as its parameter and adds it to the calling object. subtract—subtracts two Quadratic equations by subtracting corresponding values of a, b, and…
Create a class named Pet (similar to the one discussed in this chapter), which has the following properties:• Name—The Name property holds the name of a pet.• Type—The Type property holds the type of animal that a pet is. Example values are “Dog”, “Cat”, and “Bird”.• Age—The Age property holds the pet’s age.Demonstrate the class in an application that creates an object of the class and lets the user enter the name, type, and age of his or her pet. This data should be stored in the object. Retrieve the pet’s Name, Type, and Age properties and display their values on the screen.
Write a class named Aircraft that has the following member variables: xear - An variable that holds the aircraft's model year. make - A string object that holds the make of the aircraft Qwuer: A string object that holds the type of owner of the aircraft. speed - An int that holds the aircraft's current speed. altitude, An int that holds the aircraft's current altitude. engine type- a String value to hold the type of the engine the aircraft has In addition, the class should have the following member functions. Constructor - The constructor should accept the aircraft's owner and make arguments and assign these values to the object's owner and make member variables. The constructor should initialize the speed variable to 0 and the altitude variable to 0. Accessors - Appropriate accessor functions should be created to allow values to be retrieved from an object's year, make, owner, altitude, and speed member variables. Mutator - Appropriate mutator function should be created to allow the…
