From the api documentation
createNewFile
public boolean createNewFile()
throws IOException
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.
Returns:
true if the named file does not exist and was successfully created; false if the named file already exists
Throws:
IOException - If an I/O error occurred
SecurityException - If a security manager exists and its SecurityManager.checkWrite(java.io.FileDescriptor) method denies write access to the file
Since:
JDK1.2


I Hope This Helps
