Help

Java newbie here.. just started learning it (crashcourse) this summer at my job (consisting of programming in java...)

i'm still not acquainted with too many of Javas errors/bugs and how to fix them. I was looking for a bit more help than the impersonal documentation.

What should I look for with a Java.lang.NullPointerException error? I know the basics, but feel free to review them again if you wish. I've reviewed the particular function/method that is in error, and I know I'm missing something. More information is available upon request!

Thanks a lot you guys! :o)
