How long would it take an experienced Java developer to study for the exam with your book?
Not sure if this question can be answered definitively because it depends on a lot of factors. Most importantly because experience != expertise. We have seen experienced programmers fail the exam and, here on the ranch itself, 16 yr olds with no experience pass the exam.
Still, if I were to guess, an person with 2 yrs of Java development experience should be able to do it in a months time with a 2hr per day schedule. But really, one would have to determine this for themselves. Take a few mock exams, see where you stand, and then you will have a better idea of how much effort you need to pass this exam.
