Stupid mistake, maybe?

Hi, I'm trying to make a simple program that will read through a list and check and remove any repeated lines. However, it only reads and checksthe first line before getting a NullPointerException error while checking it under the "contains" void. Help is appreciated, thanks.

Full stack trace please! And maybe say which line of your code it is referring to because we're all lazy here and don't like counting to 110 or whatever.
