I don´t advice to use raw sockets to upload FTP files, instead use something like SimpleFTP it's easier to use and it will save you a lot of time. And since you're learning Java, you should do it on the easiest possible way.
JavaWorld presents a discussion of some FTP client libraries. To begin with, they even teach you how to use the "built-in" Java URLConnection to do FTP with in a simple way. That should get you started!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
