welcome to the forums. Since you are new I can understand that you don't know exactly how to ask a question, so let me give you a few hints
1) this is a forum for programming problems. You do not ask for code, you write code, get stuck and ask for help. People are not going to do your work for you.
2) people are also not going to think for you. You are a developer, solving problems is your job. Research and logic are your friends, use them. But if you have problems with a choice between solutions for example, feel free to ask here.
3) when you do ask a (valid) question, please provide all the details you can. "Code for File Transfer in intranet in java" says absolutely nothing to me other than that you have some basic requirement. HOW should this file transfer be done for example? Transfer from what to where?
So please provide some more details.
