Does createNewFile() create a physical, concrete file in the working directory ?

Whenever you're shooting in the dark, my friend, get help from API documentation.


Atomically creates a new, empty file named by this abstract pathname if and only if a file with this name does not yet exist. The check for the existence of the file and the creation of the file if it does not exist are a single operation that is atomic with respect to all other filesystem activities that might affect the file. This method, in combination with the deleteOnExit() method, can therefore serve as the basis for a simple but reliable cooperative file-locking protocol.


Does that help?

And to be utterly certain, write a little program, run it and see what happens. Javac, one of the best teachers out there.
