encryption - Reading Password-Protected ZIP Files in Java -

-

i have zipped , protected file password. need retrieve file java. need unlock password , unzip java make proper connection file.

my first questions is: java unzip , unlock zipped file on local drive? (so no point protecting it?).

i have read encryption, searching easiest way here. link: http://blog.alutam.com/2009/10/31/reading-password-protected-zip-files-in-java/

my second question link above: cannot find lines pointing zipped file on local drive+ password uses unlock file (is hardcoded?)
