I am working on application that need java feature i.e. java.util.logging for logging its messages.
But when i am trying to run my application it is creating several file e.g. <filename>.log, <filename>1.log, <filename>2.log etc
I'm not sure anyone will be able to help you. You really haven't provided any information on how you are doing things. How are you using the logging? Do the multiple files get created on a single run, or do you get a new file each time you restart the program?
There are probably a million more questions I could ask, but the solution would be for you to provide a simple, self-contained example that demonstrates your problem.
There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
