1 change across 1 question — each with the behaviour it replaced, because “and how did it work before?” is the follow-up.

  • LinkedList implements Queue, making it the first standard FIFO queue.

    Before: You used Vector or a hand-rolled linked structure and did your own head/tail bookkeeping.
