It seems everything works properly but at the end of the output, I got a nullPointerException error...
What's a nullPointerException?
How can I solve this problem?
Please help...

nullPointerException occurs when you attempt to perform an operation on a null object. For instance line.indexOf("Hello"); where line is a String and null. ("" is not null. It's just the empty string)
I suspect that soemthing like that is happening in your code. Perhaps, when your code gets to the end of the file and reads null you attempt to do soemthing to it like you would do if it wasn't null. If statements would seem to be a fix.
