threaded progames

So guys I hear of many people saying single threaded programs suck. I personally program in java and i have a question. Even when i make a single thread program in java and then look @ it via jconsole it appears to have ~5-10 threads up at any time. Does that mean it's already multi-threaded and really wouldn't make a shit load of a difference since i'm already using multiple cores?

If you have a legitimate reason where execution time will greatly improve for a problem that can be split up into concurrent blocks, by all means use threads.

Don't listen to /prog/. Most of the people here are fucking retarded.
