Discussion
Which of these statements about what happens when null is passed to a TreeSet that uses natural ordering is correct?
Answer: D
A sorted set has to place every element, and with natural ordering that means calling compareTo on it, which fails on null. HashSet and LinkedHashSet accept a single null because a hash-based structure never needs to order its contents.
