Write a program that includes an Employee class that can be used to
calculate and print the take-home pay for a commissioned sales employee.
All employees receive 7% of the total sales. Federal tax rate is 18%. Retirement
contribution is 10%. Social Security tax rate is 6%. Write instance
methods to calculate the commission income, federal and social security tax
withholding amounts and the amount withheld for retirement. Use appropriate
constants, design an object-oriented solution, and write constructors.
Include at least one mutator and one accessor method; provide properties for
the other instance variables. Create a second class to test your design.
Allow the user to enter values for the name of the employee and the sales
amount for the week in the second class.
