Java App fail to run twice

[Johnny]

I just wrote a program that take a text file and runs fine the first
time but as I input another file and run it again it freezes in the
middle of my scanner method. Don't know why..

ps I did close the scanner after the first run

I think we're going to need an SSCCE to help you with that one:

http://sscce.org/

Short, Self Contained, Correct (Compilable), Example

* Short (Small) - Minimise bandwidth for your example, do not bore
the audience.
* Self Contained - Ensure everything is included, ready to go.
* Correct - Copy, paste, compile, see-the-error is the aim.
* Example - Displays the problem you are trying to solve.

..Don't know why..

Perhaps that would depend on the code you did not
show us. How about posting an SSCCE*?

ps I did close the scanner after the first run

Good, good.. BTW - did you have a question?

I got it fixed, forgot to cancel old thread.

That should not matter. Once you exit those old threads are gone, no?
Was it still running when you started again?

That's what I though too, at first. Then it occurred to me that he maybe
meant the news-thread. He forgot to cancel the original post..

Maybe.

No i meant the new thread from the program, because my program never
exits out, it suppose to be able to run over and over again without
exiting. Originally I am running a swing worker in the background
therefore when the first run is done i forgot to cancel or done that
thread and when i run the program the second time the worker starts
another thread. Two parellel thread running using the same scanner.
Thats when it messes up, therefore when I cancel the first thread
after the first run, everything is fine.

No i meant ...

So - you've decided /not/ to post an SSCCE?
