- build와 gradle폴더에
gitignore추가 부탁드려요. - 공통적으로 코드에 마지막 줄이 없는 경우가 있습니다
이 또한 컨벤션이니 맞춰주세요 - 이번 주차의 실습 요구사항을 맞춰주세요
재리뷰 요청드립니다.

전형적인 절차지향코드 형태입니다.
객체지향을 살려서 코드를 구현해 주세요.
선언과 할당이 분리될 필요가 없습니다

매직 넘버란 코드 안에 작성된 구체적인 숫자 혹은 문자열을 말합니다. 그리고 매직 넘버의 단점은 아래와 같습니다.
- 의미를 이해하기 어렵다.
- 복수의 장소에서 사용된다면 변경하기 힘들다.
그런 매직 넘버는 의미를 나타낼 수 있는 상수로 치환하여 코드의 가독성을 높여 보는 것은 어떨까요?

주석이 필요한 코드는 충분한 의미를 담지 못했다고 생각됩니다
| validationResult[1] = 1; | ||
| break; | ||
| } | ||
| } |
| return 1; | ||
| } | ||
| nameCount.put(carNames[i], "이것은 존재한."); | ||
| } |
array for car name validation has been changed to primitive type variables. and method for car name validation has been changed stream form. I madd main method length short.
I replaced magic number, SCANNER to not magic number, scanner.
