Java How To Program (Early Objects)(10th Edition) Chapter 9

Exercise 9.15

(Creating a New Subclass of Employee) Other types of Employees might include SalariedEmployees who get paid a fixed weekly salary, PieceWorkers who get paid by the number of pieces they produce or HourlyEmployees who get paid an hourly wage with time-and-a-half1.5 times the hourly wagefor hours worked over 40 hours.

Create class HourlyEmployee that inherits from class Employee (Exercise 9.14) and has instance variable hours (a double) that represents the hours worked, instance variable wage (a double) that represents the wages per hour, a constructor that takes as arguments a first name, a lastname, a social security number, an hourly wage and the number of hours worked, set and get methods for manipulating the hours and wage, an earnings method to calculate an HourlyEmployees earnings based on the hours worked and a toString method that returns the HourlyEmployees String representation. Method setWage should ensure that wage is nonnegative, and setHours should ensure that the value of hours is between 0 and 168 (the total number of hours in a week).

Use class HourlyEmployee in a test program thats similar to the one in Fig. 9.5

IIMPORTANT NOTE!!: Please add detailed, but brief comments to most, if not all of the code to explain what is being used in the code and what is does so I have a better understanding of the code. Also I've tried previously already posted answers to this question but they had errors and I couldn't figure out why. Thank you.
