Hi Guys . As a part of my college project, i have to build a Peer To
Peer file sharing system in Java. Can anyone tell me how should i
start. I tried studying the source code of Limewire but it was quite
difficult.

Think about what kind of p2p system you want ...
I think creating the overlay graph that you then use for communication
would be the first job.
Very easy might be a random Graph created by a pointer push and pull
operation.

when you did this you may want to create a sort of DHT on this random
graph ... if you want something state of the Art take a look at
distributed weighted hashing (i.e.
http://cone.informatik.uni-freiburg.de/pubs/WDHT.pdf ) .. probably not
to easy to code but they allow you very powerful searches in your p2p
network...
For filetransfer you could create a little instance of your random graph
to which all can join that want sth...
And then either wither use some BT like protocol or have a look at
Microsoft's Avalanche .. if you can implement Network Coding in in a
perfomant way this may rock.
Well the question is .. how large is the course .. how many hours can
how many people invest into the project.
