Threads Chapter Question 15: yo yo dude dude program.

When I run this program I get output as :

yo yo dude dude

Whereas K & B book says :

the output could be yo dude dude yo

[Ankit: added code tags and fixed subject line]

Please UseCodeTags when you post source code (you've been here for a while, you should understand by now how to use code tags...).

Pay attention to the word "could". It doesn't say it's always "yo dude dude yo".

Do you understand yourself why you get the output that you do?

Generally speaking, SCJP questions have extremely precise answers, but thread questions, by the very nature of how threads get scheduled often CANNOT have such precise answers...

So, it's really common to see imprecise words in threads questions like: "probably" or "could" or "possible" or "tends" or "most likely". Of course it's essential that you pay attention when a question uses a word like that - it means that you can't exactly predict the outcome of some code, but that you can know some things about how it will run.
