I'm reading for OCJP 7 exam. I am reading all the topic from SE7 point of view. Will there be questions from SE 6 in the exam? Eg:For Files and File Handling topic, I am reading nio.2 .. This was introduced in SE 7. Will there be questions on files prior to nio.2 (i.e how it was done in SE 6 before nio2)? Is it part of the OCJP 7 Programmer 2 exam?
