Extract a specific directory inside a ZipFile

[vast shuttle]

Okay, so I've been banging my head on this one for a while, and I cannot figure out how to do this programmatically.

I have a ZipFile (Foo.zip) that has a directory inside of it (root/bar) with it's files (root/bar/fizz.file, root/bar/bang.file) that I want, but nothing else from the file. I know that I can unzip the entire file into a temporary directory, but I want to try to extract it without doing that.

I tried to get the ZipEntry of the directory I want, but I can't figure out how to get the files inside that entry out. I can't seem to get a working iterator either.

What am I missing?

You have to inspect all ZipEntries and for each check whether it is in the desired directory. If so, extract it.
