Payroll Program in Java Using Method Overloading

 Machine Problem in Java

Payroll that includes five double field variables that hold hours

worked, rate of pay per hour, withholding rate, gross pay, and net pay, and three String

field variables that holds the last name, first name and position of the employee. 

Create three overloaded computeNetPay() methods. 

When computeNetPay() receives values 

for hours, pay rate, and withholding rate, it computes the gross pay and reduces it by

the appropriate withholding amount to produce the net pay. 

When computeNetPay() 

receives two arguments, they represent the hours and pay rate, and the withholding

rate is assumed to be 10%. 

When computeNetPay() receives one argument, it

represents the number of hours worked, the withholding rate is assumed to be 10%,

and the hourly rate is assumed to be 59.65. 

Name the program as Payroll.java

The gross pay is computed as hours worked multiplied by pay per hour.

Display the last name, first name, position, total pay for the hour's work, withholding

rate, gross pay and the net pay of the employee.
