I am trying to read in data from a text file. How it works (well supposed to heh) is like this... I have a text file with info for 13 people (each person has 15 attributes). The text file starts with the number 13 so that the first line read in is the number 13, and the program uses that number as a loop counter. I have displayed the Employment.java code and the Print.java code. Everything is done in employee and then print is used to display it.
Also the text file contents have been displayed.
The code compiles fine, but I get a run time error... here it is:
init:
deps-jar:
compile:
run:
Begin Month: Begin Day: Begin Year: Name: Address: Phone #: SSN: Age: Sex: Employer Name: Employer Address: Employer Phone #: Years of Employment: Title: Salary:

I'm using the code to just make it visually nicer...

I know this is a lot, but I've been racking my brain trying to figure out why this isn't working. I've done similar programs, but with less attributes per person. I really hope someone can help me out with this. Thanks!
