버퍼스트림이나 파일스트림같은 경우에는 자동으로 `try()` 내부에 선언되어 있을 경우 `close()`를 호출해주는 것으로 알고 있습니다. public static void main(String args[]) { try ( FileInputStream is = new FileInputStream("file.txt"); BufferedInputStream bis = new BufferedInputStream(is) ) { int data = -1; while ((data = bis.read()) != -1) { System.out.print((char) data); } } catch (IOException e) { e.printStackTrace(); } } 제가 궁금한 점은 TheadLocal.remove() 메서드가 위와같이 호출이 되는지와 만약 안되면 따로 이 처리에 대한 메서드를 구현시켜서 동작시켜야하는지가 궁금합니다.
'use strict' ; var point = 45645 ; var get = { point : 5645641231 } var book = { point : 123 , get : function (){ return this . point ; } } var obj = book . get . bind ( book ); // 실행하는것이 아니라 book.get이라는 똑같은 함수를 다시 만들어 this바인딩컴포넌트에 book오브젝트를 바인딩 console . log ( book . get ) console . log ( obj ) console . log ( book === obj ) console . log ( obj ()) //123 console . log ( obj . call ( get )) //123 bind()로 만들어진 함수에 call을 해도 결과가 변함없는것은 내부프로퍼티인 [[BoundThis]] 를 먼저 참조하기 떄문인가요? 이말은 즉, call과 apply를 쓸 수 없단 말인건가요? 감사합니다.
코드에 빨간줄 간것도 아닌데 h2를 실행시키고 MemberServicIntegration - 회원가입 란을 실행하면 오류가 납니다 ㅠㅠ 오류는 아래와 같습니다. 해결방법좀 알려주시면 감사하겠습니다. antlr.NoViableAltException: unexpected token: Member at

우선 개인키를 이용하여 암호화를 하였는데(아래 사진이 개인키 위치 설정(?)) 위의 파일을 이용하여 암호화 복호화 과정에는 공개키가 필요 .. 복호화를 위해서는 공개키가 필요한데 공개키에 대한 설정을 한적이 없습니다. 어떻게 복호화가 되는지 궁금합니다. 시스템 내부적으로 저 개인키를 통하여 공개키를 스스로 만들어서 알아서 복호화가 되는 것인가요??
깃헙 저장소 이름은 반드시 유저이름.github.io 로 변경/생성 하셔야하며 코드 도중 등장하는 CommentWidget.tsx 에서의 src 는 const src ='<https://utteranc.es/client.js>'; 에서 < > 를 뺀 https://utteranc.es/client.js 만 입력하시면 정상적으로 동작할겁니다
만약 다음과 같이 인풋을 받았다고 가정하겠습니다. @Valid @ModelAttribute ItemDto itemDto 이 경우에, 각 필드에 대한 검증은 ItemDto 내의 @NotBlank, @Max, @Min과 같은 어노테이션으로 해결하고, ObjectError의 경우 ItemDtoValidator를 만들어 Validator를 구현하여 @InitBinder로 등록해두는 건 안되나요..?
질문창에 code sample사용이 익숙치 않아서 사진으로 대체하겠습니다 위와 같이 Robot class를 정의한 뒤, droid 객체를 만들어 보았습니다. 이후 __age가 아닌 age에 접근해서 값을 변경하는 코드를 작성했는데, 작동을 했고, 기존에 있던 __age가 아닌 새로운 변수 age가 만들어진 뒤, 100으로 초기화가 되는듯 한 현상이 일어났습니다. 그리고 color라는 class에서는 정의한 적이 없는 변수에 31을 대입해도 잘 작동을 하는것을 확인하였습니다. class에서 선언한 적이 없는 변수를 할당한다는것이 선뜻 자연스럽게 받아들여지지 않아서 이런식으로 코드를 짜는 경우가 실제로도 있는지, 이런걸 방지하기 위한(외부에서 새로운 변수를 할당?)방법은 무엇이 있는지 궁금해서 질문 남깁니다! 감사합니다.
class Student:public Person { private: int m_intel public: Student (const std:: string&name_in ="No Name", const int &intel_in=0) :Person(name_in),m_intel(intel_in)//여기서 오류발생 {} } 선생님께서 여기서 오류가 나는 이유가 default constructor가 없기 때문에 생긴다 하셨는데 Student 의 생성자가 호출될때 string&name_in 여기에 "No Name" 으로 initialize 가 되고 "No Name"을 가진 변수 name_in을 Person(name_in)이런식으로Person class을 생성하면서 보내기때문에 Person class 의 생성자 Person(const std::string & name_in) :m_name(name_in) {} 이 생성자 만으로도 충분히 작동이 될꺼같은데 안되는 이유가 무엇인가요? Person(const std::string &name_in)이 생성자의 name_in 에 "No Name" 이 들어가서 m_name 에 "No Name"을 할당시켜주므로 default constructor 없이도 잘 작동될꺼 같은데 안되는 이유를 잘 모르겠습니다
안녕하세요, 오늘 코딩공부를 시작한 학생입니다. 1강에서 페이스북의 색깔을 가져오셨다고 하셨는데 어떻게 가져오셨는지 궁금합니다. 페이스 북의 홈페이지에 직접가서 개발자 도구로 가져오는 건가요? 아니면 그림판같은 다른 도구로 색깔을 지정해서 알 수 있는건가요? 만약 개발자 도구로 가져오는거면 #숫자 를 육안으로 찾아서 복붙을 해야하는건가요.. 저같은 경우에는 비슷한 색을 사용하는 op.gg의 색을 가져오려 하는데 잘 모르겠어서 질문드립니다. 2021. 07/15 익명의 학생 올림.
