채점사이트에 dfs 방식으로 풀이후 제출해보았는데 오답처리가 되어 강사님 강의를 확인했는데 Integer[] arr 을 static 처리를 했는지 여부를 제외하고 전부 코드가 같았습니다. 강사님의 코딩을 그대로 클론하여 검사받아도 오류가 나오고 제가 짠 코드로도 오답이 나오는데 혹시 이유를 알 수 있을까요? 코드 첨부하겠습니다. package section8; import java.util.Arrays; import java.util.Collections; import java.util.Scanner; public class p05 { static int n; static int money; static int answer = Integer.MAX_VALUE; public static void DFS(int count, int sum, Integer[] arr){ if(sum > money)return; if(sum >= answer) return; if(sum == money){ answer = Math.min(answer,count); } else{ for(int i = 0; i<n; i++){ DFS( count+1,sum+arr[i], arr); } } } public static void main(String[] args) { Scanner sc = new Scanner(System.in); n = sc.nextInt(); Integer[] arr = new Integer[n]; for(int i = 0; i<n; i++) arr[i] = sc.nextInt(); money = sc.nextInt(); Arrays.sort(arr, Collections.reverseOrder()); DFS(0,0, arr); System.out.println(answer); } }
[질문 내용] 강의 내용 중 "JPA와 DB 설정 동작 확인"의 20분 경부터 나오는 ./gradlew clean build 를 실행하다가 -> 아래 화면 캡처와 같이 java.lang.IllegalStateException at DefaultCacheAwareContextLoaderDelegate.java:132 에러가 발생했습니다. Test 파일 2개 모두 동일한 에러 메시지입니다. 커뮤니티의 답변 및 구글 검색을 통해 문제를 해결하려 했으나, 해결하지 못해 문의드립니다. (커뮤니티 답변에서 저와 동일한 에러를 만난 경우는 진도가 더 나간 상태에서 발생한 에러였으며, 구글링에서는 대부분 AWS배포와 관련되어 이 에러가 발생하고 그것을 해결한 케이스였습니다.) Test 파일 2개는 아래와 같이 작성되었습니다. 커뮤니티 답변을 모두 확인한 것은 아니었기에, 혹시 저와 동일한 상황에서 동일한 에러가 해결된 경우가 있다면 링크를 부탁드립니다. (혹, 답변을 위해 더 공유해야 할 내용이 있다면 알려주세요)
질문을 찾아봤는데 없는것 같아서 질문 드립니다! 혹시 특정 Service만 OSIV를 끄고 커넥션을 유지하는 방법은 없을까요? 이전 강의에서 hibernate.default_batch_fetch_size는 전체 사이즈를 정하고 @BatchSize처럼 개별적으로 사이즈를 정하듯이 OSIV는 개별적으로 on/off는 불가능한지 궁금합니다.
23분쯤에 UpdateItemDTO를 service계층에서 만들고 controller로부터 String name, int price... 이렇게 따로 받지말고 dto로 한번에 받는게 좋은 설계다 라고 말씀 해주셨는데 그러면 Controller에서 service 계층의 UpdateItemDTO를 알고 있어야 DTO를 service계층으로 보내줄텐데 이렇게 되면 UpdateItemDTO를 service계층에 만드는것은 문제가 따로 없는건가요? 서로 다른 계층에 대해서는 서로 몰라야 한다고 생각했는데 헷갈려서 질문 드립니다.
안녕하세요. 연관관계에 대해서 의문이 생겼습니다. 24분 쯤에 foreign key를 update 한다고 하셨는데 foreign key가 업데이트 되는 것이 실무적으로 발생해도 되는 경우인가요? pk를 참조하고 있기 때문에 개념상으로는 update 되어서는 안되는 데이터라고 생각했는데 상황적으로(팀을 바꾸는 상황)는 update 되는 것이 맞다고 여겨져서 제가 잘못 알고 있는 것인지 궁금해졌습니다. 감사합니다.

안녕하세요~! 본 강의에서는 사용되지 않았지만 다중공선성 제거를 위해 VIF 10 이상인 피쳐들은 drop하는 게 성능에 더 좋다고 하여 해당 방법을 적용하였는데 오히려 RMSE값이 0.3~0.5 정도 커지는 결과가 나타났습니다.(선형회귀, 릿지, 라쏘) VIF 제거 외에는 강의해주신 내용도 거의 유사한 방식으로 전처리 적용하였습니다. 1. VIF 10 이상인 피쳐들을 제거하는 게 예측률 향상에 무조건 좋은 것은 아닌건가요? 2. 만약 그렇다면 다중공선성 제거를 위한 추가적인 기법이 있을 것 같은데, 대표적으로 활용되는 방법이 어떤게 있을까요? 3. 마지막으로, VIF 10 이상인 피쳐들은 제거하여 성능이 향상되는 데이터셋의 대표적인 예와, 적용이 잘 안되는 예가 있을까요? 이번에도 애매한 질문을 드리는 점 죄송합니다. 아시는 수준에서 답변 주시면 정말 감사하겠습니다^^
안녕하세요. 이번에 새로 다시 프로젝트를 만들어 실행해보려고 강의에서 보여주신 대로 메이븐으로 만들어봤는데 강사님께서 만드시는 화면과 제가 만드는 화면이 다르더라고요. Archetype 과 version 을 필수로 입력해야 넘어가지던데 여기에 뭘 추가해줘야하나요? 혹시 몰라 jpa-maven-archetype 을 선택해봤는데 아래처럼 에러가 납니다. 자바 8로도 해봤는데 똑같은 증상을 보입니다!
Student 클래스에 보시면 public Student() { korea = new Subject(); math = new Subject(); } public Student2 (int id, String name) { studentID = id; studentName = name; korea = new Subject("국어"); math = new Subject("수학"); } 이렇게 있는데 저기 빨간 글씨인 첫번째 퍼블릭 스튜던트는 없어도 되는거 아닌가요? 두번째 퍼블릭 스튜던트가 있으면 첫번째건 없어도 되는거죠? 또 첫번째가 있다면 두번째가 없어도 되는 거 맞나요? 둘다 있을 필요는 없지 않나요?

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요. [질문 템플릿] 1. 강의 내용과 관련된 질문인가요? (예) 2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예) 3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예) [질문 내용] 안녕하세요 이번에 스프링부트를 공부해보려고 이사이트에 찾았습니다. vscode가 친숙해서 vscode로 개발을 진행하는데 자바파일 실행시 아래와 같은 오류가 계속 뜨게됩니다... 어떻게 해야 해결할 수 있을까요?
안녕하세요? 훌륭한 강좌 덕분에 처음 해보는 Flutter지만 쉽게 배우며 많은 재미를 느끼고 있습니다. 감사하다는 말씀 드리고 있습니다. 3장 샘플중에 [한줄 일기] 샘플소스 중에 정확히 어떤 의미인지 잘 이해가 안가서 여쭤봅니다. 질문 1) // createdAt은 중복될 일이 없기 때문에 createdAt을 고유 식별자로 사용 // createdAt이 일치하는 diary 조회 Diary diary = diaryList.firstWhere((diary) => diary.createdAt == createdAt); => 는 {return} 과 동일하다고 알고 있었는데요. 뒤에 createdAt (작성일)이 같은지 bool 형태로 리턴된 후 diary 형태의 인스턴스를 리턴하라는 의미인지요? --------------------------------------- 질문 2) TextField ( ... 중략 ... onSubmitted: (_) { // 엔터 누를 때 작성하기 createDiary(diaryService); Navigator.pop(context); }, ), 위에서 (_) 의미가 파라미터를 원래 있는데 안 넣을때 쓰는 건지요? 어떨때 쓰는 걸까요?
시퀀스 증가값이 50이라고 가정했을때 최초실행시 시퀀스를 두번 불러와서 1과 51을 가져오는것으로 이해했습니다. 이때 만약 allocationSize = 1 이여도 최초실행했을때는 1~51까지 insert를 모았다가 보낸다고 생각해도 될까요? 최초인 1~51이 지난후에는 52,102,152,,,로 한개씩 insert로 보낸다고 생각이들어서요. 즉 최초 실행시 allocationSize가 시퀀스 증가값보다 작다면 jpa는 1부터 1+[시퀀스증가값]을 사용할 수 있기때문에 allocationSize보다 더 많은 값인 1부터 1+[시퀀스증가값]만큼 보낼 수 있다 라고 이해해도 될까요?
