Using FileRead As Database

I remember, it's possible to collect multiple parameters from each line in a .txt file (with commas used as delimiters to separate each parameter on each line). My EmployeeData.txt file looks like this:

EDR2014,Bob,Marley,02/12/2011,1000.00
ARR1234,John,Fuzzy,03/23/2013,12.00
XXX0666,Matt,Pagel,08/10/2011,23.00
DIE4273,John,McLane,07/22/1995,45.00
FUK0330,Kevin,Young,12/02/2003,7.00

NFN7734,Sam,Peterson,08/01/1999,8.00

the parameters of each line are: employeeNum, firstName, lastName, hireDate, payRate

To match the specifications in the following EmployeeInfo.java class:

Java Code:

package employeepunch;
//import org.joda.time.DateTime;
import java.io.*;

public class EmployeeInfo {

[code]...

The validation of making sure the employee uses the correct format while entering his employee number is just the first part. I also need to add validation code to make sure his employee number matches one of the ones in the EmployeeData.txt file (shown earlier above).
