Summary

Threads are a powerful concept that is implemented with a small number of classes and interfaces in Java. By supporting multithreading in your applications and applets, you make the programs more responsive and can often speed up how quickly they perform tasks.

Even if you learned nothing else from this hour, you now have a new 21st century term to describe your frenzied lifestyle. Use it in a few sentences to see if it grabs you:

• "Boy, I was really multithreading yesterday after Mom was indicted for mail fraud."
• "I multithreaded all through lunch, and it gave me gas."
• "Not tonight, dear, I'm multithreading."
