I have following questions, can someone tell me if i answered correctly

no

Custom Validators in JSF will be executed during the Render phase, is it correct? 
yes

yes

Does Throwable class in Java extend Exception class? 
no

In Java, Can I restart a completed thread? 
yes

never worked with jsf or portlets, so I'll leave it to that, you're definitely wrong in your last answer, though.

'Can I restart a completed thread?'
No, you can't. what you can do is start a new one of the same type, just not the completed one. that one's gone.
