Question
This has been done before on here but did not recieve good reviews or was not done properly. Thanks to anyone who can help.
Develop a Java application to calculate the monthly paychecks for a number of different types of employees. The employee types are created in a subclass array based on parent base class Employee. Initial code is provided for each class and for a driver class. You will need to compile each Java source file (provided below) separately, in its own file since they are public classes, to create a .class file for each, ideally keeping them all in the same directory. You should first compile and execute the original classes and then make your customer modifications for this program.
You should compile Date.java first, then Employee.java, then CommissionEmployee.java, then BasePlusCommission.java, then HourlyEmployee.java, then SalariedEmployee.java, and finally PayrollSystemTest.java. And maintain this compilation order when you make your customized modifications to these classes later.
As part of the modifications you need to make to the supplied code, you are to prompt the user for all the data that is now provided in the code for the class PayrollSystemTest (i.e. instead of using these values from their declaration in the code, get data from prompting the user for it, one value at a time). All program output, including prompts and results and all program input must be done from the PayrollSystemTest class.
In addition you need to add a new private instance field "birthDate" to the Employee class. The “birthDate” field must be a Date data type, not a String! Add get and set methods to Employee class for this new birthDate field.
The birthDate field must be determined from separate integer values, supplied by the user, for the birth month, day, and year. As with all other inputs, these three birth date components must be prompted from and input to class PayrollSystemTest. Once input, these three parameter values must then be supplied to the appropriate modified employee subclass constructor, and then the subclass constructors supply these three values to their parent class, a modified Employee class constructor.
The single birthDate field of a Date data type must be declared and initialized in the Employee class.
In class PayrollSystemTest create an array of Employee variables to store references to the various employee objects. In a loop, calculate the monthly paycheck amount for each Employee (polymorphically), and add a $100.00 bonus to the person's monthly payroll amount if the current month (i.e. November) is the month in which the Employee's birthday occurs.
Your program should input data and create the five employees below on the version of the program you submit for grading. Your program must calculate their monthly salaries for November (assumed to be the "current" month). Assume that the monthly salary is simply four times the weekly salary.
one Salaried Employee with a weekly salary of $1000 and a birthday of January 1, 1960,
one Salaried Employee with a weekly salary of $1000 and a birthday in this month (November 1, 1961)
one Commission Employee Worker with a gross weekly sales of $12,000 and a 5% commission rate and a birthday of February 1, 1962,
one Base Plus Commission Employee with a gross weekly sales of $10,000, a 3% commission, and a $500 base weekly salary with a birthday of March 1, 1963, and
one Hourly Employee with a wage of $20/hour working for 40 hours and a birthday of April 1, 1964
You should make up your own employee names for the five required employees above. Make sure you create the employees in the order above.
In prompting the user for all input values for the five employees above, your program essentially replaces the existing main() method of PayrollSystemTest.java. You may user whatever input class you want (e.g. JOptionPane, Scanner). Keep all other lines of the code in PayrollSystemTest as they are originally, including the code that gives a 10% increase to the Base Plus Commission employee.
You will probably find it helpful to prompt for the worker type first. You may
hardcode "November" as the special bonus month.
Since the outputs are to be for monthly paychecks, just multiply the weekly
salaries, weekly output quantities, and weekly hours by 4. Display your results
for each worker's salary after all data for that employee type has been entered
and the salary determined.
Your output should appear like the example below (using the current examples in the code for PayrollSystemTest (the "Employees processed individually" portion isn't shown, and monthly salaries are shown below as required by this program vs. weekly salaries that would be produced from the unmodified code). Note that the test data is shown below. Your five employees will create a different set of outputs. After you verify that the original program produces these results you can remove the output statements for this original data and just keep what you need for your five employees.
Employees process polymorphically:
salaried employee: John Smith
social security number: 111-11-1111
date of birth: 01/02/1960(current code won't do this but yours must)
weekly salary: $800.00
earned $3200.00
hourly employee: Karen Price
social security number: 222-22-2222
date of birth: 01/02/1960(current code won't do this but yours must)
hourly wage: $16.75; hours worked: 40.00
earned $2680.00
commission employee: Sue Jones
social security number: 333-33-3333
date of birth: 01/02/1960(current code won't do this but yours must)
gross sales: $10,000.00; commission rate: 0.06
earned $2400.00
base-salaried commission employee: Bob Lewis
social security number: 444-44-4444
date of birth: 01/02/1960(current code won't do this but yours must)
gross sales: $5,000.00; commission rate: 0.04; base salary: $300.00
new base salary with 10% increase is: $330.00
earned: $2120.00
Employee 0 is a SalariedEmployee
Employee 1 is a HourlyEmployee
Employee 2 is a CommissionEmployee
Employee 3 is a BasePlusCommissionEmployee
