움 제가 2단계에서 피드백 드리지 못한부분이 있어서 요기에 남길게요!!
- COMMA_SEPARATOR가 LottoPlay에 위치할 이유가 있을까요? StringUtil에서만 사용되는 것 같아요!
- purchasedLottos는 MutableList가 아니라 List여도 충분할 것 같아요 :)

- Boolean타입이여도 충분하지 않을까요?
- 해당변수에만 리턴값을 명시하신 이유가 있을까요?

보통 로또에서 2등을 5개 일치 + 보너스 일치로 이야기하는데요! 해당 enum의 값이 BONUS가 되어야하지 않을까요?

지난주 리뷰에서 LottoNumber를 값객체로 wrapping하는 예시를 보여줬는데요! 이번에 값객체를 만들어보시면 어떨까요?

현재는 lastWeekWinningNumbers를 List로 넘겨주고 있지만, 해당 변수도 하나의 Lotto객체로 만들어보면 어떨까요??
WinningLotto와 같이 Lotto와 BonusNumber를 가지고 있는 객체를 만들어볼 수 있을것 같아요!
