How to make a thread never be terminated?
Please support our Java advertiser: Programming Forums - DaniWeb Sister Site

Hello everyone,
I have a very important thread in my application and I do not want it to be terminated accidently, or in other words, if it is terminated for some reason (for example, be terminated by some unhandled Runtime exceptions), I want it to restart automatically.
I am wondering whether Java has build-in approach to implement this goal. If Java does not have build-in approach to implement this, I am wondering where can I find similar sample source codes or tutorials?
regards,
George

Well, if the JVM dies any thread in it dies as well so you can't have a thread that never dies at all.
Other than that, you can track whether your thread is alive of course.
Thread has a method for that called isAlive() which returns true if the thread is not dead (but has been started).
You can of course NOT restart a dead thread, so if it dies you'll have to create a new thread for it and start that.
I've found good threading tutorials very hard to find. I'm also still looking for a good threading book, the one I did get (Taming Java Threads) is probably the worst book on programming I've ever had the displeasure of reading and is the first programming book I ever tossed into the trash that wasn't completely outdated.

Thanks jwenting,
Both your reply and your advice are very helpful.
