a. Create a payroll JApplet named J CalculatePay that allows the user to enter two double values: hours worked and an hourly rate. When the user clicks a J Button, gross pay is calculated. Display the result in a JTextFi el d that appears on the screen only after the user clicks the JButton. Save the file as JCalculatePay.java.

b. Modify the payroll applet created in Exercise 8a so that federal withholding tax is subtracted from gross pay based on the values in Table 17-1. Display the gross pay, tax amount, and net pay. Save the file as JCalculatePay2.java.
