Thanks...But I need to know if I can replace exp2 by null.Will null be printed on the stack trace or any error will be generated?

Then maybe you need to read below. There is only two questions in the exam on assertions so I wouldn't focus on them only. http://java.sun.com/developer/technicalArticles/JavaLP/assertions/As far as mock exams then whats wrong with Google?

Thanx...I am trying lot of mock exams from google, but I wanted to know which one will be very near to the main exam pattern and difficulty.Regarding Assertions,is null valid to use in the second exp in an assert statement?
