Thanks for Reply

What i want exactly is ,In java I created 100 files using files concept. like file1,file2,......file100

in some directory say "c:/krishna".

Now My question is while running my program (creation of files) i want to see if directory is changed i want to

perform some action .is there any events like directory or folder changed events in java.

You have several option for that.

1. You can simple deals with the file count in that folder. But you have to do it periodically.

2. (this is what I suggest you) If all the files are created from your own applications you must have a notion about the file creating one by one. So perform your action within that level.

Java 7 has that functionality; it has a Watch Service that can notify you whenever there is a change in a directory; Java 6 and below don't have it and you should implement it yourself by periodically scannnng the entire directory for changes. This approach doesn't scale well though ...

kind regards,

I want the file or file path to be passed as argument to another function
