java.util.Timer doesn't work

[FET]

Hi all,
I have an application that displays a Swing GUI. The application
writes its logs to a certain file. I would like to have a thread that
checks the file every, say 10 seconds, and if it is found to be
deleted, creates a new file. I have made a class that extends
TimerTask and in the run method, it calls file.exists() and
file.createNewFile(). Then I have set timer.schedule ( task, 0,
10000). But the code never gets called.

Should I just use plain ol' awt threads ? I think Timers is a more
sophisticated mechanism. But it doesn't seem to be working.

Please advise.

Thanks in advance.

Best regards.

Check the FileMonitor class at

It uses java.util.Timer and works perfectly.

As Andrew said, please post a complete example that fails, including the
code to prove that the timer task is never called (println or whatever).
This should work.

There's no such concept as "AWT threads". Plain old Java threads would
work, but you're right that java.util.Timer is a better idea. Let's see
if we can fix that.
