Question

Purpose: This assignment is designed work with text files, string manipulation and

inheritance.

Assignment Description:

A Java program should be created to read an employee text file (Information.txt) and

decide from the employee number and shift which department and shift the employee is

assigned. A list of the employees and their information should be listed to the monitor as

well as written to a text file named Department.txt.

Instructions:

Create a class named Employee including a constructor and the necessary accessor and

mutator methods. The class should keep the following information in fields:

o Employee Name

o Employee Number in the format X-NNN, where each N is a digit and X is a

letter which can be one of the following:

? H - represents Human Resources

? A - represents Accounting

? P - represents Production

? S - represents Shipping

o Hire Date

Next, write a class named ProductionWorker that inherits from the Employee class. Include

a constructor and the necessary accessor and mutator methods. The ProductionWorker class

should keep the following information in fields:

o Shift Number which is an integer and can be one of the following:

? 1 - represents Morning Shift

? 2 - represents Swing Shift

? 3 - represents Night Shift

o Hourly Pay Rate

Input: The input file will be named Information.txt. One record (line) will contain the

employee name, employee number, hire date, shift number and pay rate each separated by

spaces. A sample text file is below.

Jane Rivers, A-902, 05/16/2001, 1, 16.25

Bob Cox, S-823, 06/21/1990, 2, 17.50

Ann Ramsey, A-715, 02/12/1998, 1, 16.25

Joseph Chandler, P-723, 12/22/2000, 3, 14.35

Arnold Kennedy, S-133, 08/10/1999, 2, 18.20

Larry Huber, P-198, 02/12/2000, 3, 17.25

Annette Wilson, H-501, 04/04/1995, 1, 20.25

Robert Ferguson, H-674, 04/10/2002, 2, 16.50

Ava Gaines, H-434, 01/05/2000, 3, 15.65

Output: Output should consist of a listing of the employee name, employee number,

employee's department, hire date, shift name and pay rate This information should be

displayed on the monitor as well as written to a text file named Department.txt. The format

for writing to the monitor could be as follows:

Jane Rivers A-902 Accounting 05/16/2001 Morning Shift 16.25

Bob Cox S-823 Shipping 06/21/1990 Swing Shift 17.50

Ann Ramsey A-715 Accounting 02/12/1998 Morning Shift 16.25

Joseph Chandler P-723 Production 12/22/2000 Night Shift 14.35

Arnold Kennedy S-133 Shipping 08/10/1999 Swing Shift 18.20

Larry Huber P-198 Production 02/12/2000 Night Shift 17.25

Annette Wilson H-501 Human Resources 04/04/1995 Morning Shift 20.25

Robert Ferguson H-674 Human Resources 04/10/2002 Swing Shift 16.50

Ava Gaines P-434 Production 01/05/2000 Night Shift 15.65

Requirements:

? Inheritance must be used as described in the instructions
