Question 2:
You can read about daemon threads and how they are different from user thread here: http://www.javaranch.com/ubb/Forum24/HTML/001830.html
I do not think you are required to know about daemon threads for the exam, but it is good if you do � you feel more confident.
 
I agree. Here's the link: http://aspose.com/file-tools
