Can this be done?

Hello,
I'm new to Java. I have no background about how programming in Java is but I'm planning to learn how things are done.

I just have one question before I start. I've got an idea about a mobile application that I've been thinking to work on for a regional programming competition in Kuwait, my hometown. It's basically a program that allows people in a LAN to communicate through their mobiles without the need of using their emails. I'm thinking of a shout box or something similar. Something quick for a professor and a student to communicate for short messages without the need to exchange emails or phone numbers.

I've got 8 months to work on learning Java and creating my first "draft" of code.

Do you think it can be done?

What's wrong with email or calling/texting? :P

As for is it possible... Possibly. You'd need some sort of identification, otherwise your message will be sent to no one or everyone. I'm not sure what the capabilities of Java ME are, but a quick google search should solve that problem. That's a pretty ambitious project if you don't know Java yet. I'd suggest you start with something that doesn't require learning network protocols.
