java - Do I need to close files I perform File.getName() on?

I'll be having lot of files in a directory. I'll be just getting the file names using File.getName() and log them to a log file. I presume, I don't need to close the file since I'm not doing any read/write operation in it.

Is this correct?

You never have to close Files, because it is basically a representation of a path. Only Streams and Readers/Writers. In fact, File does not even have a close() method.
