ManyToOne 모듈에 default EAGER로 적힌 부분을 LAZY로 바꾸면 안되나요??? 다른 사람과 함께 협업할 때 문제가 발생할 여지가 있어서 모듈을 바꾸지않고 직접 @ManyToOne(fetch=FetchType.LAZY)로 바꾸는 건가요???

이 부분 편집이 뭔가 이상한거 같습니다. 강의평가 욕설관련도 이 부분에 해당하는거같아요!

int main() { int n; int i = 0; int cnt = 0; scanf_s("%d", &n); while (i <= n) { i++; if (i % 2 == 0) { cnt++; } } printf("%d", cnt); }

16 비트든 32비트든 맨 앞자리는 음양 을 구분하는 용도로 쓰이고 나머지 15 ,31 비트로 정수를 표현 하는건가요?

6을 2진수로 변환하면 110  7은 111  n트로 표현 하는 경우에는 정보가 n자릿수보다 작다면  앞 0을 붙여서 자릿수를 채운다고 생각하면 되나요?

안녕하세요 영한님 강의 너무 감사하게 잘보고 있습니다. 강의를 너무 잘보고 있던 와중에 Junit 테스트 중 에러가 발생하여 몇일째 해결을 못하고 있어서 이렇게 문의 드립니다 ㅠㅠ 영상 강의 중 회원테스트 강의에 MemberServiceTest 를 Junit으로 테스트시 오류메세지가 올라옵니다  이해가 잘 가지 않는 부분이  MemoryMemberRepositoryTest는 Junit으로 테스트시 문제가 없었으나 MemberServiceTest만 오류가 발생합니다 또한 내부의 내용을 전부 지운 후 메서드 이름만 있는 상태에서 실행해도  다음과 같은 에러가 올라옵니다 내용은 다음과 같습니다

강의대로 input 태그 중 radio를 이용해 성별을 선택할 수 있도록 했을때 중복선택이 가능하고 한번 누르면 취소가 안됩니다. 중복을 허용하지 않도록 하는 방법이 있을까요?

선생님,for문[코딩시간]의 답은 어떻게 되는 걸까요??

ㄴ이렇게 코드를 작성해서 네이버 로그인 해보려 했더니 안되던데..  방법이 있나요? ^^;   그리고 셀레늄으로 카페 매일 간단한 인사말 같은거 자동으로 남기는 것도 가능한가요? 

현재 리스트에 보여지는 값은 로컬스토리지의 키 값을 배열에 담아서 뿌려주는거 같은데 값을 가져 오기 위해서는 아래와 같이 수정을 해야 하지 않는가요?  변경전:  this.todoItems.push(localStorage.key(i)) 변경후:  this.todoItems.push(localStorage.getItem(localStorage.key(i))); 로컬 스토리지의 키와 값을 동시에 가져 올수 있는 그런 메소드는 없는지요 그렇다면 구지 두번이나 로컬스토리지에 접근해서 값을 가져오지 않아도 될것 같은데요 바쁘시겠지만 답변 부탁 드리겠습니다.

안드로이드 스튜디오 버전이 어떻게 되나요?

문법 오류라는데 무슨 문법이 틀렸는지 모르겠습니다. 문법오류가 아니라면 제가 뭐 파일을 잘못 건드린걸까나요??

import VueRouter from 'vue-router' import Vue from 'vue' Vue.use(VueRouter) 부분에서 에러가 나 페이지가 제대로 렌더링 되지 않습니다. 개발자도구 콘솔에 뜨는 메시지로는 , Uncaught TypeError: Cannot read property 'use' of undefined at.... 이라는 메시지가 뜹니다.  vue 버전은 3.0이고, vue-router는 3.4.3 입니다.  어떤 부분이 문제인지 모르겠습니다. cdn으로 vue-router를 가져오는 경우, 잘 되는데, Vue.use 이 부분에서 계속 에러가 뜨네요.

listview일때 render_to_response를 오버라이딩했었는데 BaseListView일때 get 메소드에 똑같이 render_to_response는 있지만 listview처럼 아래에 render 메소드가 정의되어 있지않아요.. 상관없는건가요?

동영상보고 똑같이 해봤는데 jsp는 되고 servlet은 404 에러가 뜨네요 해결방법 있나요??
