what do you mean by "edit it' and "add some lines"?


There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

Why are you using StringTokenizer, which is a legacy class?
What is supposed to happen and what goes wrong? Please look at this FAQ.
Why are you doing anything to a file in system32?
Why have you written an empty catch block?
 
It is sorta covered in the JavaRanch Style Guide.
