Discussion
Which of these packages contain all the collection classes?
Answer: B
Correct answer: java.util
The collection framework - List, Set, Map and their implementations, along with Collections, Arrays and the iterators - lives in java.util. It must be imported explicitly, unlike java.lang, which is imported automatically and holds the core language types such as String, Object and the wrappers.
