Hi,
I am a new bie to eclipse.In the following scenario i want to know
whether i can generate random filename while creating a file using IFile

I am writing data to a file and while writing to a file i am checking for
fatal errors and when error occurs i want to revert back to the previous
state of file by storing the data in a temporary file and revert the file
to previous state with the data in temporary file.

Pls suggest me how to generate random filename while creating a file using
IFile in eclipse.

Maybe a name like "errorxxxxxxxxx" where xxxxxxxxxxx is a timestamp

You just need to create a unique name as String and use it as filename.
Get the file handle e.g. with IFolder.getFile, then create the file with
IFile.create.

You should also take a look at the workspace history features of
eclipse. Changes to a file are recorded and can be reverted by the
resource framework, so you wouldn't have to do that manually. I haven't
used it myself yet, so I can't help you with that.
