Change file name and its extension before output it Java -

lets i've got file in d: has filepath as:

d:\work\2012\018\08\2b558ad8-4ea4-4cb9-b645-6c9a9919ba01

at moment name of file not meaningful. doesn't have format. have ability create file object above filepath in java , alter name , format before writing bytes. new path following:

d:\work\2012\018\08\mywork.pdf

after changes have been made, should still able gain access original file per normal.

i know type of file , name there won't problem getting details.

just rename file:

file file = new file(oldfilepath); boolean success = file.renameto(new file(newfilepath));

you give filename , utilize same parent current file:

file file = new file(oldfilepath); file.renameto(new file(file.getparentfile(), newfilename));

java file filepath

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
