Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object class’s ToString() method and returns a string that contains the name of the class (using CetType and the Letter’s data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.

You are designing an application to rate your professors.a. Professors have the following properties: first name, last name, universityname, subject, and ratings for overall quality (1.0-5.0) and level of difficulty(1.0-5.0). Your class should have instance variables of the appropriatetype for each property.b. Your class should have two constructors: one that takes all properties, andone that takes only first name, last name, university name, and subjectand sets both of the ratings to an appropriate default value.c. You should provide accessors (getters) and mutators (setters) for firstname, last name, university name, and subject.d. Your class should provide a method to add a new rating for the professor.It should take two arguments: one for overall rating and one for level ofdifficulty, with values from 1 (awful) to 5 (awesome). Each time a newrating is provided, your class should calculate the average rating for theprofessor and update the appropriate variable for each.e. Your class…
Create a class called FinalGrade that is used to represent the points obtained in the letter grade of CSC 110 by different students. The FinalGrade class should include three pieces of information as instance variables—studentName (type String), studentID (type String), and pointsObtained (type int). Your class should have a constructor that initializes the three instance variables. Provide a set and a get method for each and every instance variable. In addition, provide a method named computeLetterGrade that returns the letter grade obtained by the student taking the pointsObtained as an argument. For the grading policy refer to CSC 110 grading scheme specified in syllabus. Write a test application named FinalGradeDriver that creates at least 3 different objects of class FinalGrade and test all the methods of class FinalGrade.

- Which of the following statements is false? a. A class can contain only one constructor. b. An example of a behavior is the SetTime method in a Time class. c. An object created from a class is referred to as an instance of the class. d. An instance of a class is considered an object.arrow_forwardWrite a program named DemoJobs for Harolds Home Services. The program should instantiate several Job objects and demonstrate their methods. The Job class contains four data fields—description (for example, wash windows), time in hours to complete (for example, 3.5), per-hour rate charged (for example, $25.00), and total fee (hourly rate times hours). Include properties to get and set each field except the total fee—that field will be read-only, and its value is calculated each time either the hourly fee or the number of hours is set. Overload the + operator so that two Jobs can be added. The sum of two Jobs is a new Job containing the descriptions of both original Jobs (joined by and), the sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. Harold has realized that his method for computing the fee for combined jobs is not fair. For example, consider the following: His fee for painting a house is $100 per hour. If a job takes 10 hours, he earns $1000. His fee for dog walking is $10 per hour. If a job takes 1 hour, he earns $10. If he combines the two jobs and works a total of 11 hours, he earns only the average rate of $55 per hour, or $605. Devise an improved, weighted method for calculating Harolds fees for combined Jobs and include it in the overloaded operator+() method. Write a program named DemoJobs2 that demonstrates all the methods in the class work correctly.arrow_forwarda. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).arrow_forward

The price field requires a get accessor but no set accessor. Also include a ToString() method that returns a string constructed from the values of the fields. Derive two subclasses MattedPhoto and FramedPhoto. The MattedPhoto class includes a string field to hold a color, and the FramedPhoto class includes two string fields that hold the frame’s material (such as silver) and style (such as modern).

- Create an application named ShapesDemo that creates several objects that descend from an abstract class called GeometricFigure. Each GeometricFigure includes a height, a width, and an area. Provide get and set accessors for each field except area; the area is computed and is read-only. Include an abstract method called ComputeArea() that computes the area of the GeometricFigure. Next you will create three additional classes derived from the GeometricFigure class. Name these derived classes: Rectange, Square, and Triangle Create a Rectangle is a GeometricFigure whose area is determined by multiplying width by height. Create a Square is a Rectangle in which the width and height are the same. Provide a constructor that accepts both height and width, forcing them to be equal if they are not.
