java

Write our Test Driver program that tests our Classes and Class Relationship

How we calculate Net Pay after calculating taxes and deductions taxes:

regNetPay = regPay - (regPay * STATE_TAX) - (regPay * FED_TAX) + (dependents * .03 * regPay )

overtimeNetPay = overtimePay - (overtimePay * STATE_TAX) - (overtimePay * FED_TAX) + (dependents * .02 * overtimePay )

Example printPayStub() output:

Employee: Ochoa
Employee ID: 1234
Hourly Pay: $25.00
Shift: Days
Dependents: 2
Hours Worked: 50
RegGrossPay: $1,000.00 OvertimeGrossPay: $375.00 TotalGrossPay: 1375.00
RegTaxes Deducted: $150.00 ($100.00 State $50.00 Federal )  
OvertimeTaxes Deducted: $56.25 ($37.50 State $18.75 Federal)            
TotalTaxesDeducted: $205.75 ($137.00 State $68.75 Federal)
Tax Deductions: $75.00 RegPay, $60.00 Overtime, $15.00 total deductions
NetRegPay:   $910.00      NetOvertimePay:  $333.75       TotalNetPay: $1,243.75

Answer 1

update 2 methods

1) PrintPayStub in payroll.java

2)calculateRegPay in worker.java

please find the below code for the same
