The wrapper classes, Boolean, Byte, Short, Character, Integer, Float, Double are used anytime you need to represent a primitive value as an Object.
Yes, the exam does include questions on wrapper classes.
The next version of my mock exam will have a new set of questions on the Byte wrapper class. I hope to have it up by 5:00 PM Pacific Time today, Friday, August 9.
