The daemon status of a thread can be changed at any time using the Thread.setDaemon method??

why this is wrong ???is it that the status can be changed only at the begining of the thread???

The reason being that you cannot change the Daemon status of the thread after the start() method gets called otherwise a n IllegalThreadStateException is thrown. You should call the method Thread.setDaemon() before calling the start method on the thread.

I hope you got it.

in the K&B book i found nothing about deamon threads, so may i conclude this will not be on the exam?

also for the "you can call a method on a thread object after you invoke start, unless you get IllegalThreadStateException", nothing found in the book, and on school it was burned in like hell
