I am a 3rd year university student in computer science. My goal is to become a very good Developer in JAVA. I have made 2 of my university projects in java. I have a newbie knowledge about JAVA and i also have good skills in Object oriented programming concepts. But i zero knowledge in networking no desktop applications. So, I decided to try some open source projects. read them thoroughly and practice on them. I am looking for advice from where to start? any suggestions?
