The program has the following algorithm:

• In the main method do the following operations,
• Get the employee name, number of hours worked in a week, hourly pay rate, federal tax withholding rate and state tax withholding rate from the user.
• Calculate gross pay by call the method.
  • Multiply hourly pay rate and hours worked in a week for calculating the gross pay.
• Calculate federal withholding by call the method
  • Multiply gross pay and federal tax withholding rate for calculating the federal withholding.
• Calculate state withholding by call the method
  • Multiply gross pay and state tax withholding rate for calculating the state withholding.
• Calculate total deduction by call the method
  • Adding federal withholding and state withholding for calculating total deduction.
• Calculate net pay by call the method
  • Subtracting gross pay and total deduction for calculating net pay.
