안녕하세요, 강사님. Shape 클래스 실습을 진행한 결과물을 공유드립니다. 실습 내용을 바탕으로 도형의 크기를 부모 클래스에서 관리하고, 각 자식 클래스에서 기본 크기를 지정할 수 있도록 생성자를 구성해 보았습니다. 시간 괜찮으실 때 구현 방향에서 어색한 부분이나 개선하면 좋을 점이 있는지 간단히 봐주시면 감사하겠습니다. 또한 이번 실습에서 추가로 생각해 보면 좋을 내용이 있다면 함께 알려주시면 감사하겠습니다. 감사합니다. package java2_30; import java.util.Scanner; /** * 화면에 출력할 수 있는 도형의 공통 부모 클래스입니다. * * 현재 실습에서는 삼각형과 정사각형만 다루므로, * 가로와 세로를 구분하지 않고 하나의 size 값으로 크기를 관리합니다. */ abstract class Shape { private final int size; protected Shape(int size) { this.size = size; } protected final int getSize() { return size; } /** * 각 도형의 모양을 콘솔에 출력합니다. */ abstract void render(); } class Rectangle extends Shape { private static final int DEFAULT_SIZE = 4; public Rectangle() { this(DEFAULT_SIZE); } public Rectangle(int size) { super(size); } @Override public void render() { for (int i = 0; i < getSize(); i++) { for (int j = 0; j < getSize(); j++) { System.out.print("*\t"); } System.out.println(); } } } class Triangle extends Shape { private static final int DEFAULT_SIZE = 5; public Triangle() { this(DEFAULT_SIZE); } public Triangle(int size) { super(size); } @Override public void render() { for (int i = 0; i < getSize(); i++) { for (int j = 0; j <= i; j++) { System.out.print("*\t"); } System.out.println(); } } } class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("사각형은 0, 삼각형은 그 외 숫자를 입력하세요: "); int input = scanner.nextInt(); Shape shape; if (input == 0) { shape = new Rectangle(); } else { shape = new Triangle(); } shape.render(); scanner.close(); } }
- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요. 안녕하세요. 최근 현차하고 한화에서 인적성을 채용 프로세스에 도입했다는데, 혹시 코테보는 sw 직군들도 다 인적성 쳐야하나요? 그럼 sw 직군은 인적성하고 코테 다 보는 걸까요? 감사합니다.
강사님 안녕하세요, 좋은 강의 여러번 반복해서 잘 듣고 있습니다. 재고 감소와 비교했을때 차이점이 궁금하여 문의드립니다. 안녕하세요 강사님 이전 재고 관리 강의와 차이에 대해 궁금합니다. 이전 질문을 참고하였으나 추가로 더 궁금한게 있어서 문의드립니다. 재고 감소와 쿠폰 발급의 차이점이 너무 헷갈려서 정리하고 있습니다. 두 경우 모두 한정된 수량을 여러 요청이 동시에 차지한다는 점에서는 비슷해 보입니다. 그렇다면 쿠폰도 이벤트 테이블에 잔여 수량을 100개나 300개로 설정하고, 재고처럼 수량을 차감한 뒤 사용자 쿠폰을 생성하는 방식으로 구현할 수 있지 않을까요? 강의에서는 쿠폰 발급의 정합성을 위해서 전체 로직에 락을 걸 필요가 없다고 하셨는데, 그러면 반대로 재고 감소 같은 경우도 마찬가지로 재고 감소의 정합성을 위해 전체로직에 락을 걸 필요 없이 다른 방법으로 하는게 더 나은 방법 아닌가요?? 비슷해 보이는 한정 수량 문제를 서로 다르게 푼 이유를 잘 모르겠습니다 ㅠㅠ
안녕하세요, 저는 회사에서 next.js로 포팅하여 개인적으로 좀 공부하고 있는 학생입니다. 현재 2강 할 일 관리 앱을 보면서 저희 회사의 작업 방식을 함께 생각해봤는데 저희 회사는 꼭 필요한 부분 (iron-session을 이용하여 세션을 가져온다거나)을 제외하고는 죄다 클라이언트 컴포넌트로 바꿔서 사용하고 있습니다. 그래서 이 작업을 진행하면서도 클라이언트 컴포넌트로 모두 바꾸어 진행한다면 어떨까라고 생각이 들었었는데 과제에서는 최소한의 컴포넌트만 클라이언트 컴포넌트로 바꾸라고 하신 이유가 궁금합니다. 감사합니다!
안녕하세요 큰돌님 코딩 살구 클럽 4-C 문제에 N과 인구수에 대한 범위가 기재가 안되있는 것 같은데 혹시 수정 가능할까요? 그리고 4-D 문제 풀이했는데 주차 진행도에 반영이 안됩니다! 중복된 문제라서 뭔가 버그가 있는 것 같습니다.! 1-G 문제도 프라이빗 케이스에 문제에서 주어진 조건의 패턴 말고 다른 패턴이 입력되거나 (시작이나 끝에 *이 위치하는 경우는 없다고 문제에서 이야기함), 입력 문자열에 소문자말고 숫자나 대문자가 포함되어있어서 실패가 나네요.!
커버링 인덱스가 아니라고 가정한다면 클러스터링 인덱스까지 2번의 B+Tree 탐색을 하지만 커버링 인덱스라면 이런 탐색을 한번 줄여 발생하는 IO 작업을 최적화 하는것으로 이해 했습니다 커버링 인덱스 말고도, 자주 사용되는 페이지의 위치를 자동으로 InnoDB에서 어댑티브 해시 인덱스라는 공간에 저장 하는것으로 알고 있는데 이 방식도 IO 작업을 최적화 하는 것인지 궁금 합니다
데이터 검증 강의에 대한 내용은 감명깊게 수강하였고, 강의의 쿼리 외적으로 질문이 있습니다ㅎㅎ 저는 이 강의의 문제만 보고 빅쿼리에서 스스로 문제 풀기를 3일간 도전하였는데, 결국 풀지 못한 채 강의를 보게 되었습니다! 제 사고 과정은 다음과 같습니다. 1. 총 배틀 횟수 계산이 난해하다. 2. '각 트레이너'의 정보를 얻으려면 battle 테이블과 trainer 테이블을 조인하여 t.trainer_id = b.player_id를 확인해야 할 것으로 예상된다. 3. trainer 테이블을 기준으로 battle 테이블을 LEFT JOIN 한다. 그런데 강의 03:57 ~ 04:03 부분을 확인해보니, player_id를 기준으로 trainer_id를 매핑시키는 방식의 쿼리를 작성하셨더라고요! Q. 제가 최초에 trainer_id 컬럼을 기준 삼았다고 가정할 때, trainer_id = player_id 이 불편함을 깨닫고 player_id = trainer_id 으로 관점을 바꾸면 좋겠다고 생각할 근거가 있다면 무엇일지 궁금합니다..! 나름 최선의 표현으로 글을 다듬었지만, 이 질문이 난해할 수 있다고 생각하고요..! 원하는 답을 얻지 못할 확률이 높다고 생각하면서도 혹시나 하여 질문드립니다. 감사합니다!
