There is a generic system call for that, fopen(). Have a look at its man page and report back if anything in there is unclear.

First off, i'd like to question the rationale behind 764. That would mean to give execute rights to the owner and i would be quite surprised if you would want to create an executable.

Second, the path: "\opt\sys\doc" is not a path but rather a filename. Since you do not need to escape regular characters you could also write "optsysdoc" to the same effect. So, what is the path?

I hope this helps.

\opt\sys\doc this is the path and files will be created under that path

You might want to start by reading the JAVA API documentation of File class:
File (Java Platform SE 7 )
