Java irc bot problems

Question

Hello,
Im trying to write a irc bot in java. So far it works well. I am trying to test
for a quiet room. If room is quiet I want my bot to say something. Only problem
is that my test for "quiet" are not working. Could someone take a look and
tell me what Im doing wrong.
Thanks,
jd

I believe what you want is a thread that waits for x seconds before doing something (ie say something). If after x seconds the thread hasnt been killed/reset then do something and reset the thread.
Your listen method should reset the thread everytime its called.
when I say reset the thread I mean the thread will be doing a wait() and when it wakes up it should check a flag to see whether or not the room is still quiet. Your listen() method should set this flag.
Thats a broad outline any hoo.
