Once you have written the class, write a program that creates three RetailItem objects and stores the following data in them: Description Units in Inventory Price Item #1 Jacket 12 59.95 Item #2 Designer Jeans 40 34.95 Item #3 Shirt 20 24.95FootballTeam ClassDefine a class in the FootballTeam java file that will represent a football team as follows: ● The class has the following three fields which cannot be accessed outside of the class. • name of the team (teamName)• number of wins (numOfWins)• number of losses (numOfLosses)● Write a constructor that accepts the name of the team (n), the number of wins (w), and the number of losses (l) as arguments and sets the class properties to those values. ● Write methods that return the name of the team (getTeamName), the number of wins (getNumOfWins), and the number of losses (getNumOfLosses). ● Next, write a method to increase the numbers of wins by 1 (increaseWins) and another method to increase the number of losses by one (increaseLosses). ● Write a method that returns true when a team has a “good record,” meaning the team has more wins than losses(getRecord).● Write a driver program in the FootballTeamDemo class. ○ In the main method, construct a FootballTeam named…Attached you will find a Java class called Employee. This class includes a constructor which sets name to blanks and salary to $0.00 and a constructor which sets name to a starting name and salary to a set amount. Additionally, the class includes methods to set the name and salary and return the name and salary. You will create a new class called Manager that inherits from the attached class Employee. Add a field named department of type String. Create a get and set method for the department variable. Supply a method toString that prints the manager's name, department, and salary. But you may not change anything in the Employee class. You will then create a test class that uses the Manager class. The test class should prompt the user to enter name, department and salary. This information should be stored in an array. Upon entry of an employee records, the program should output the information you entered.
- C++ Stars This lab exercise will practice creating objects with constructors and destructors and demonstrate when constructors and destructors are called. Star Class Create a class, Star. A Star object has two member variables: its name, and a solar radius. This class should have a constructor which takes a std::string, the name of the star, and a double, the solar radius of the star. In the constructor, the Star class should print to the terminal that the star was born. For example, if you create a Star as follows: Star my_star("Saiph", 22.2); Then the constructor should print: The star Saiph was born. In the destructor, the Star class should print to the terminal that the star was destroyed, along with the number of times the volume of the sun that that star was, formatted to two decimal places. Hint: use the following line to set the precision to 2 decimal places: std::cout << std::fixed << std::setprecision(2); For example, when my_star above has its destructor called,…Create a class Employee a) private and static field nextAvailableID (int): create a static constructor to initialize this field to a random number (hint: you can use Random class). You can assume that IDs are numbers between 1-9999. Since nextAvailableID is static, all the Employee objects will share this field. b) with properties FirstName (string) LastName (string), ID (int): make it read only to allow initializing only with a constructor and then no more. c) Add a constructor to allow setting properties FirstName and LastName. Hint: ID will be initialized to nextAvailableID (make sure to increment nextAvailableID by one) Add ToString Method to display the full name and ID of the employee Then, write a Main method to test your class Employee.

An Invoice should include four pieces of information as instance variables a part number (type String), a part description (type String),a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoice Amount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0. Write a test application named InvoiceTestMJibranAkram that demonstrates class Invoice’s…
