queue instead of the default type "T"


wrapper type Correct Answer: an immmutable type that is basically a reference
to a primitive type: it looks diff:

Integer - int


Character - char


Boolean - boolean


Double - double


diamond operator Correct Answer: when you first create a Queue you dont
have to specify twice the type of the queue(meaning you don't have to say:
Queue<Integer> qi = new Queue1L<Integer>();


you can just say: Queue<Integer> qi = new Queueu1L<>();


the diamond operator is <> and it tells you that you're still using the actual type
of Integer


auto-boxing/unboxing Correct Answer: a feature for wrapper types that lets it
be a lot more fluid and be able to be used almost as if they were a primitive
type
