java.net.BindException: Address already in use: bind

I got this example to work but I'm getting a strange bind warning when I run this program. How do I resolve this problem?

Port 4567 is in use. Make sure that you killed previous app and that port 4567 is free. There are plenty resources how to check which ports are in use and how to kill application related. If however port 4567 is used by system, try to change it "port(4568)" command. How to change port see documentation:
