wite a java program that will compute an employee's net pay.you will have the following 1) Employee class(external) 2) Boss Class(external) 3) CommissionWorker(external) 4) PieceWorker Class (external) 5) HourlyWorker Class(external) 6) NetPayrollTest Class(driver)
add private instance variables birthdate, deduction rate, and social security number to Class Employee
Assume this payroll is proccessed once per month. then, as your program calculates the payroll for each Employee(polymorphically)add $100.00 bonus to the person's payroll gross amount if it is the month in which the employee's birthday occurs.
The Employee class will contain a private static variables for counting the number of employees and
the total net payroll amount; also static methods used to obtain the current number of employees and the net payroll amount.
The NetPayrollTest application program will send to the external class/es via instantiation all the information each employee have ss3, and birthdate as part of their data. All employee's have a standard deduction of 22.5%
Within the program demonstrate the try/catch logic all classes packaged as follows except the NetPayrollTest which will be in the root: CIS2421/Programs/Assignment
note: all source files will be created in the root dir. and when compiled the class file/s will be directed to the respective package. NetPayrollTest will be compiled an run from the root dir.
I need help bad this is what I have so far
