Create a class called Complex for performing arithmetic with complex numbers. Complex numbers have the form realPart + imaginaryPart * i where i is -1 Write a program to test your class. Use floating-point variables to represent the private data of the class. Provide a constructor that enables an object of this class to be initialized when it is declared. Provide a no-argument constructor with default values in case no initializers are provided. Provide public methods that perform the following operations: a) Add two Complex numbers: The real parts are added together and the imaginary parts are added together. b) Subtract two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand, and the imaginary part of the right operand is sub- tracted from the imaginary part of the left operand. c) Print Complex numbers in the form (a, b), where a is the real part and b is the imaginary part.

Create four (4) Java classes named Color, Model, Car, and CarDemo. In the Color class, create an enum named Color that consists of six (6) colors of your choice. In the Model class, create an enum named Model that contains the following values: SEDAN, SUV, CONVERTIBLE, and HATCHBACK. In the Car class, declare three (3) private fields: int variable named year A Model object named model A Color model named color Add a constructor for the Car class with three (3) parameters: yr (int), model (Model), and color (Color). Inside the constructor, assign yr to year, m to model, and c to color. Add a display( ) method that prints the three (3) Car object's data. In the main method of the CarDemo class, instantiate two (2) Car objects assigning values to them using enumeration values for the models and colors. Example: Car car1 = new Car(2014, Model.SUV, Color.RED); Add two (2) statements to display the data of the two (2) Car objects.
Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variable Part number(type String) Part description(type String) Quantity of the item being purchased (type int) 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 InvoiceTest that demonstrates class Invoice’s capabilities.
My professor has given me additional information for this question: Create a class named CollegeCourse that includes data fields that hold thedepartment (for example, ENG), the course number (for example, 101), thecredits (for example, 3), and the fee for the course (for example, $360). All of thefields are required as arguments to the constructor, except for the fee, which iscalculated at $120 per credit hour. Include a display() method that displaysthe course data. Create a subclass named LabCourse that adds $50 to the coursefee. Override the parent class display() method to indicate that the course isa lab course and to display all the data. Write an application named UseCoursethat prompts the user for course information. If the user enters a class in any ofthe following departments, create a LabCourse: BIO, CHM, CIS, or PHY. If theuser enters any other department, create a CollegeCourse that does not includethe lab fee. Then display the course data. Save the files as…

Create a class named CarRental that contains field's for: renter's name, zip code,size of car, daily rental fee, length of rental (in days), and total rental fee. The class should include a constructor that requires all the rental data except the daily rate and total fee, which are calculated based on the size of the car: economy size ($ 29.99 per day), midsize ($ 38.99), and full size ($ 43.50). The class also includes a display() method that will display all the rental information. Create a subclass name LuxuryCarRental.
