(Polymorphic Application) You’ve been asked to develop a flight simulator that will haveelaborate graphical outputs. Explain why polymorphic programming could be especially effectivefor a problem of this nature.
(Rectangle Class) Create class Rectangle. The class has attributes length and width, each of which defaults to 1. It has read-only properties that calculate the Perimeter and the Area of the rectangle. It has properties for both length and width. The set accessors should verify that length and width are each floating-point numbers greater than 0.0 and less than 20.0. Write an app to test class Rectangle.

- (Default Constructor) What’s a default constructor? How are an object’s data members initialized if a class has only an implicitly defined default constructor?arrow_forward(java programing) Define a student class. A student has the following attributes: Firstname: the name of the student lastname: the name of the family Gender: which can be male or female status: which can be equal to freshman, sophomore, junior, and senior gpa: The average which value is between 0.0 to 4.0 Then define the following methods for the student class. • The show_myself: method will simply print all the attribute variables when called upon the object. This method has no input arguments. • The study_time: method will increment the gpa of the student according to the following formula: ` gpa = gpa + log(study_time)`. The only input argument of this method is the variable study_time. • In addition make sure that the gpa variable never exceeds 4.0 even if the student studies for a very long time. • Any necessary methods that is required for such class.arrow_forward(Constructor Overloading) Can a Time class definition that includes both of the followingconstructors:Time( int h = 0, int m = 0, int s = 0 );Time();be used to default construct a Time object? If not, explain whyarrow_forward
- (Rectangle Class) Create a class Rectangle with attributes lengthand width, each of which defaults to 1. Provide methods that calculatethe rectangle’s perimeter and area. It has set and get methods for bothlength and width. The set methods should verify that length andwidth are each floating-point numbers larger than 0.0 and less than 20.0.Write a program to test class Rectangle.(Java Programming Language)arrow_forward(CLO3) Read the following description and answer the following questions about it: Problem Description: A car dealership allows customer to purchase their new cars with different options. At this time, those options are color, model, and air condition, as shown below in class CustomerOrder. Of course, the dealership wants the software to be flexible enough to be able to add more options in the future, if needed. CustomerOrder -carColor: String -carModel: String -hasAirCondition: boolean Q1) Write the full required code in Java to use the Builder design pattern to create class CustomerOrder. Q2) Write a Java main() method to create an object of class CustomerOrder with color "red" and without air condition.arrow_forward(Inheritance Advantage) Discuss the ways in which inheritance promotes software reuse,saves time during program development and helps prevent errors.arrow_forward
- (Polymorphism and Extensibility) How does polymorphism promote extensibility?arrow_forward(True/False) Only existing operators can be overloaded.arrow_forward(Java) Create a Test class that instantiates three farmers with different attributes that invokes their methods. Be sure to test the farmerMeeting() method.arrow_forward
- (Invoice Class) Create a class called Invoice that a hardware store might use to representan invoice for an item sold at the store. An Invoice should include four data members—a part number (type string), a part description (type string), a quantity of the item being purchased (typeint) and a price per item (type int). Your class should have a constructor that initializes the fourdata members. A constructor that receives multiple arguments is defined with the form:ClassName( TypeName1 parameterName1, TypeName2 parameterName2, ... )Provide a set and a get function for each data member. In addition, provide a member functionnamed getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by theprice per item), then returns the amount as an int value. If the quantity is not positive, it should beset to 0. If the price per item is not positive, it should be set to 0. Write a test program that demonstrates class Invoice’s capabilitiesarrow_forward(Topic:Software Design) Q# 1) Write the difference between Logical and Physical software design, Also give some examples of both.arrow_forward(The Person, Student, Employee, Faculty, and Staff classes) Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number, and email address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the person's name. Draw the UML diagram for the classes and implement them. Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods. Note: Code language must be Javaarrow_forward
