问题
I am trying to make an FTP client from scratch in Java and so far I can connect to the FTP server. Im not allowed to use Apache to download a file, so my question is: how do I download a file from a remote FTP-server? I've now spent the last 2 days trying to find a guide but it seems impossible to find one which does not require Apache.
Any help is appreciated, thank you.

You can do this quite straightforward with an URLConnection. An example is outlined in this post.
