Create a class named Billing that includes three overloaded computeBill()methods for a photo book store. When computeBill() receives a single parameter, it represents the price of one photo book ordered. Add 8% tax, and return the total due. When computeBill() receives two parameters, they represent the price of a photo book and the quantity ordered. Multiply the two values, add 8% tax, and return the total due. When computeBill() receives three parameters, they represent the price of a photo book, the quantity ordered, and a coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 8% tax and return the total due. Write a main() method that tests all three overloaded methods

Modify the Car class example and add the following:
A default constructor that initializes strings to “N/A” and numbers to zero.
An overloaded constructor that takes in initial values to set your fields (6
parameters).
accel() method: a void method that takes a double variable as a parameter and
increases the speed of the car by that amount.
brake() method: a void method that sets the speed to zero.
To test your class, you will need to instantiate at least two different Car objects in the main method in the CarDemo class.
Each of your objects should use a different constructor. For the object that uses
the default constructor, you will need to invoke the mutator methods to assign
values to your fields.
Invoke the displayFeatures() method for both objects and display the variables.
Demonstrate the use of the accessor method getColor() by accessing the color of each car and printing it to the console.
Use the method accel to increase the speed of the first car by 65 mph.

Suppose that your students take four courses - English, Mathematics, Science, and History. You should design a class that accepts all four course's numeric scores, calculates average and overall grade, and decides letter grade based on the overall grade. Your class should have a constructor, get and set methods of each course, a method that calculates the average of four courses, a method that calculates overall grade, and a method that decides letter grade. The overall grades are calculated as the following rate: Average of All four courses: 50% Quiz: 40% Attendance: 10% The letter grade is based on the following: 90.0 to 100.0 - A 80.0 to 89.9 - B 70.0 to 79.9 - C 65.0 to 69.9 - D less than 65 - F Your program demonstrates the class by asking the user to input four-course numeric scores, creating an object, and then reporting each course's score, average, overall grade, and letter grade.…arrow_forward
- Create a class named Pay that includes five double variables that hold hours worked, rate of pay per hour, withholding rate, gross pay, and net pay. Create three overloaded computeNetPay() methods. When computeNetPay() receives values for hours, pay rate, and withholding rate, it computes the gross pay and reduces it by the appropriate withholding amount to produce the net pay. (Gross pay is computed as hours worked multiplied by pay per hour.) When computeNetPay() receives two parameters, they represent the hours and pay rate, and the withholding rate is assumed to be 15%. When computeNetPay() receives one parameter, it represents the number of hours worked, the withholding rate is assumed to be 15%, and the hourly rate is assumed to be 5.85.
