help me to solve this error

Hi am sneha...my final year project is about tracking botnets..in that my first coding part includes peer registration..
peer registration:

please help me to solve this..
i got my review this week...cudn proced bcuz of this.help!!!

Please UseCodeTags next time. It adds syntax highlighting, and preserves indentation. I've added them for you this time.

You try to connect to port 80 on your local machine. That mean there must be a service running on port 80. Your program is definitely not running one; I don't see any ServerSocket anywhere.

To create a client-server pair the usual setup is common:
- The server has a ServerSocket. It listens in a loop for new Socket connections (calling accept()). For each new Socket connection it either handles it immediately (for fast request handling) or starts a new thread to handle it (if request handling takes longer).
- The client connects to this ServerSocket using the Socket constructor you're already using.

cudn proced bcuz of this.

Please UseRealWords: "couldn't proceed because of this". And please UseAMeaningfulSubjectLine next time.
