Question

JAVA LANGUAGE coding required.

You are to take the payroll file called DeweyCheatemAndHow.txt to use as input to your program and produce a file that lists all the employee and their gross pay. At the end of the file you are to show the average gross pay for each type of employee.

In order to do this, you will need to create the following classes:

Employee:

            Attribues:

                        First name

                        Last name

                        Address

                        Phone

                        SSN

            Methods:

                        Appropriate constructors

                        Set methods for first name, last name, ssn

                        Get methods for last name, first name, ssn, address, phone

                        toString

                        Equals

                        

Salaried:  (Child of Employee)

            Attributes:

                        Salary

            Methods

                        Appropriate constructors

                        Set methods for Salary

                        Get methods for Salary

                        toString

                        Pay

Hourly:  (Child of Employee)

            Attributes:

                        Pay rate

                        Hours worked

            Methods

                        Appropriate constructors

                        Set methods for pay rate, hours worked

                        Get methods for pay rate, hours worked

                        toString

                        Pay

Piece:  (Child of Employee)

            Attributes:

                        Quantity

                        Piece rate

            Methods

                        Appropriate constructors

                        Set methods for Quantity, Piece rate

                        Get methods for Quantity, Piece rate

                        toString

                        Pay

Each line in the file start with a single letter that represents whether the employee is salaried, hourly or piece rate.    The letters are s for salaried, h for hourly and p for piece rate. Below is an example of what each line will look like:

Code ssn first name last name address phone salary

s 123-45-6789 William Tell 1313 Mockingbird lane 513-556-7058 500.75

Code ssn first name last name address phone pay rate hours worked

h 123-45-6789 Scott Tell 1313 Mockingbird lane 513-556-7058 10 40.0

Code ssn first name last name address phone pay per piece number of pieces

p 123-45-6789 Chris Stevens 1313 Mockingbird lane 513-556-7058 7.50 1000

You are to process all the entries provided in the file and produce output that looks like this:

Dewey, Cheatem and How Law Firm

Payroll Report

First Name Last Name SSN  Gross Pay $XXX.

First Name Last Name SSN  Gross Pay $XXX.

First Name Last Name SSN  Gross Pay $XXX.

First Name Last Name SSN  Gross Pay $XXX.

First Name Last Name SSN  Gross Pay $XXX.

First Name Last Name SSN  Gross Pay $XXX.

First Name Last Name SSN  Gross Pay $XXX.

.

.

.

Average salaried employee gross pay:    $XXX

Average hourly employee gross pay:     $XXX

Average pieces employee gross pay:    $XXX

Please note that for this assignment you are to use the data in the file below as the source to input into your program but that the inputting is to be handled by your program prompting the user to input the information. The next assignment will address inputting directly from a file.
