after creating my class, at run-time, I'm getting a NullPointerException. I'm wondering why this is occuring. JVM doesn't like my array for some reason.
Here's my code so far:

What am I doing wrong? Any help is greatly appreciated.

Hi Brian,

The stack trace should tell you exactly what line of what file the NullPOinterException occurs on; can you tell show us exactly that line of code?

remove the semicolon :
while ((line = bfr.readLine()) != null); {

Be careful 1) You should check the size of the array returned by the split method.
Be careful 2) You are declaring a array of 4 elements, while trying access 5

In fact, you don't even need to declare a new instance.
Just do :

and check the size of the array with parts.length

Awe man, I'm an idiot. I should have guessed that it was something obvious! Doh! That did it, thanks for the insight!
I agree. Here's the link:
