Examples of java.io.File.createNewFile()

java.io.File.createNewFile()
Creates the file specified by this File. If the file already exists this method returns false. Otherwise, if the file is created successfully, the result is true. An IOException will be thrown if the directory to contain this file does not exist. @return true if this File was created, falseotherwise. @throws IOException if an I/O error occurs or the directory does not exist. @see java.lang.SecurityManager#checkWrite(FileDescriptor)
