While reviewing the study guide written by S.G. Ganesh, Hari Kiran Kumar, & Tushar Sharma for the 1z0-809 and I noticed that upper and lower bound wildcards for generics aren't covered, i.e. "? super someClass" or "? extends someClass". I'm curious to know if that means there's no questions on the exam regarding these. I've noticed other study guides cover this, but none of them state if they appear on the exam. I would think they are but Oracle just says "Create and use a generic class".
Additionally, if anyone else has used this text and knows of other topics that appear in either the guide but not the exam, or vice versa, I'd greatly appreciate the input.
Thanks!
