      • createTempFile

        public static File createTempFile​(String filename)
                           throws IOException
        Create a temporary file, which will be deleted on exit. Unlike File.createTempFile(String, String), the name of the temp file will not be randomly generated.
        Parameters:
        filename - Name of the temporary file. If the file already exists, it will be overwritten. If it exists and is a non-empty directory, an IOException will occur.
        Returns:
        The temporary file
        Throws:
        IOException - if an I/O error occurs

                              throws IOException
        Compress a single file in ZIP format.
        Parameters:
        file - The file to compress
        Returns:
        The ZIP file, which will be deleted on exit
        Throws:
        IOException - if an I/O error occurs

      • sleepQuietly

        public static void sleepQuietly​(long millis)
        A "quiet" version of Thread.sleep(long) which, rather than throwing InterruptedException, simply restores the interrupted status if interrupted. Also silently ignores invalid millis values which would normally throw IllegalArgumentException.
        Parameters:
        millis - The length of time to sleep in milliseconds. Can be negative, in which case the call will be silently ignored.

      • nop

        public static void nop()
        Perform no operation.
