Project5Read

I am taking a Java Programming Course and running into an issue with a
project. The program for this project will use the file created in
Project5Write to create a formatted report that displays a list of the
information in the file you've created. Include a line at the bottom
that lists the total number of records in the file. Call this program
Project5Read. Include a test to return an error if the filename
selected doesn't exist.

The output is:
Enter a file name:
test.dat
test.dat is a valid file.
 The file is 50 bytes long.
 It was last modified on 1247104709000 in Java Standard Time.
 The file can be read.
 The file can be written to.

Im pretty sure the problem is in my while loop but cant figure out how
to resolve it. When I remove the while loop the program reads the
first input but not the second.

Enter a file name:
test.dat
test.dat is a valid file.
 The file is 50 bytes long.
 It was last modified on 1247104709000 in Java Standard Time.
 The file can be read.
 The file can be written to.
The Employee's Number is: 1
The Employee's Name is: James Smith
The Employee's Department is: Sales
The Employee has 15 Vacation Days Available
The total number of Employees is: 2

It should read:

Any help would be great.
