JAVA Programming.

Barnhill Fastener Company runs a small factory. The company employs workers who

are paid one of three hourly rates depending on skill level:

Skill Level

Hourly Pay Rate ($)

1

17.00

2

20.00

3

22.00

Each factory worker might work any number of hours per week; any hours over 40 are

paid at one and one-half times the usual rate.

In addition, workers in skill levels 2 and 3 can elect the following insurance

options:

Weekly Cost to Employee ($)

1

Medical Insurance

32.50

2

Dental Insurance

20.00

3

Long Term DI

10.00

Write an interactive Java payroll application that calculates the net pay for a factory

worker. The program prompts the user for skill level and hours worked, as well as

appropriate insurance and retirement options for the employee’s skill level category. Use three JOptionPane Confirm Dialog Boxes (using the JOptionPane.YES_NO_OPTION) to ask the

worker if they want medical insurance, dental insurance, and long-term disability insurance, as the

worker can enroll in more than one insurance option. Use a do...while() loop to ask the user for their skill level. Keep looping until a valid skill level is provided. Use a JOptionPane to show the worker’s gross pay.

The application displays: (1) the hours worked, (2) the hourly pay rate, (3) the regular

pay for 40 hours, (4) the overtime pay, (5) the total of regular and overtime pay, and

(6) the total itemized deductions. If the deductions exceed the gross pay, display an

error message; otherwise, calculate and display (7) the net pay after all the deductions

have been subtracted from the gross. Save the file as Pay.java.
