- Write 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.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 name—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.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.
- 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…1.

- please use java to answer the following question Design and implement a class named Triangle that extends GeometricObject. The class contains: Three double data fields named side1, side2, and side3 with default values 1.0 to denote three sides of the triangle. A no-arg constructor that creates a default triangle. A constructor that creates a triangle with the specified side1, side2, and side3. The accessor methods for all three data fields. A method named getPerimeter() that returns the perimeter of this triangle. A method named toString() that returns a string description for the triangle. The toString() method is implemented as follows: return "Triangle: side1 = " + side1 + " side2 = " + side2 + " side3 = " + side3; Write a test program that prompts the user to enter three sides of the triangle, a color, and a boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties…Java question please Create a class called Account that has the following attributes: Account Client - AccountHolder Double - Balance Date - DateCreated Account() Account(Client AccountHolder, Double Balance) getAccountHolder() - Client setAccountHolder(Client) - void getBalance() - Double deposit(Double) - Double withdrawal(Double) - Double getDateCreated() - Date toString() - String compareTo(Account) - Integer equals(Account) - Double Notes: The account holder attribute will link to the Account class that you created in problem 6. Your constructor and overloaded constructor should set the date created to the current date. Your deposit method should add to the balance Your withdrawal method should remove from the balance, as long as there is enough money to withdrawalCreate 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.
