Write a class encapsulating the concept of the weather forecast, assuming that it has the following attributes: the temperature and the sky conditions (e.g. sunny, snowy, cloudy, rainy, etc.). Include a default constructor, an overloaded constructor, accessors and mutators, and the methods, toString() and equals(). Temperature, in Fahrenheit, should be between -50 and +150; the default value is 70, if needed. The default sky condition is sunny. In Addition, include a method that converts Fahrenheit to Celsius. Celsius temperature = (Fahrenheit temperature – 32) * 5/9. Also include a boolean method that checks whether the weather attributes are consistent (there are two cases where they are not consistent: when the temperature is below 32 and it is not snowy, and when the temperature is above 100 and it is not sunny). Write a client class to test all the methods in your class.

Give a complete definition of a class called TitledPerson, which youderive from the class Person in Listing 8.1. The class TitledPerson hasone additional String instance variable for a title, such as Ms., Mr.,or The Honorable. The class TitledPerson has two constructors: adefault constructor and one that sets both the name and the title. It hasa writeOutput method, a reset method, an equals method, an accessormethod getTitle that returns the title, and a mutator method setTitlethat changes the person’s title. For two titled people to be equal, theymust have the same name and the same title. You may want to use theclass Student in Listing 8.2 as a model.
In this exercise, you are going to be working with 4 classes, a Book superclass with TextBook and Novel subclasses, and a BookTester class to run your program. For the Book, TextBook, and Novel class, you will create a constructor and all getters and setters. Be sure to follow standard naming conventions for your getters and setters! Additional information for each class is below. Book Class The Book class will have a title and author as instance variables and the constructor should follow this format: public Book(String title, String author) TextBook Class The TextBook class will have a subject and edition as instance variables and the constructor should follow this format: public TextBook(String title, String author, String subject, String edition) Novel Class The Novel class will have a genre and pages as instance variables and the constructor should follow this format: public Novel(String title, String author, String genre, int pages) BookTester In the tester class, you should…
Create a class called Employee as a a derived class of the class Person. An employee record has an employee's name, address, gender(inherited from the class Person), an ID number whose type is String, an annual salary represented as a single value of type double, and a year the employee started work as a single value of type int. Your class should have a reasonable number of constructors and setter methods, as well as getter methods. Create another class containing a main method to fully test your class definition.
Write a program named SalespersonDemo that instantiates objects using classes named Real EstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each objects data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salespersons full nameâ€”the first and last names separated by a space. Then perform the following Create two child classes of Salesperson: Real EstateSalesperson and Girl Scout. The Real EstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are initialized to 0), and a commission rate field required by the class constructor. The Girl Scout class includes a field to hold the number of boxes of cookies sold, which is initialized to 0. Include properties for every field. Create an interface named ISell able that contains two methods: SalesSpeech() and MakeSale(). In each Real EstateSalesperson and Girl Scout class, implement SalesSpeech() to display an appropriate one- or two-sentence sales speech that the objects of the class could use. In the Real Estatesalesperson class, implement the MakeSale() method to accept an integer dollar value for a house, add the value to the Real EstateSalespersons total value sold, and compute the total commission earned. In the Girl Scout class, implement the MakeSale() method to accept an integer representing the number of boxes of cookies sold and add it to the total field.
I need to write a jave program to keep track of a team sport. Write a class, Team.java, that has the following: * two private instance variables: a String named color and an int named score. * a default constructor with no parameters that initializes color to "Red" and score to zero. * a constructor that takes two parameters (one for each instance variable) and sets the values of the instance variables. * a public getter and setter method for each instance variable. * a toString method that returns the color and score in the following format: "Red Team with 0 points."
Help please: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. exisiting code in different file: const double GALLONS_IN_A_CUBIC_FEET = 7.48; class swimmingPool { public: void set(double l = 0, double w = 0, double…
