변수를 초기화 한 후에 unsigned int의 사이즈를 대입하면 정상적으로 컴파일 되지만 초기화 할때부터 대입하면 왜 경고가 생기는지 궁금합니다

# 의문 - 리액트에서 배열 사용하기 1 - 리스트 렌더링 (조회) 강의 중 12분 쯤 - 리액트에서 props를 내려줄 때 undefined 값일 수도 있는데 그 때 defaultProps 문법을 사용해도 되지만 ? 문법을 사용해도 코드가 동작합니다. 두 개 중 선택할 때 뭘 기준으로 선택하는지 궁금합니다.  - 참고: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining   ```javascript=   {<h4>{diaryList ? diaryList.length : 0}개의 일기가 있습니다.</h4>}   DiaryList.defaultProps = {     diaryList: [], } ```

개발 환경   OS: M1 react-native: 0.68.2 오류 내용   안녕하세요~! TMap 을 iOS에 연동하기 위하여 설정을 해주었는데 빌드하는 과정에서 아래와 같은 오류가 계속해서 발생합니다.   TMapTapi.h 라는 파일이 깃허브 프로젝트에서는 존재하지 않는 걸로 보이는데, 구글에 검색을 해보아도 찾을 수가 없습니다. 리액트 네이티브 버전이 달라서 그런걸까요? 네이티브 모듈에 대한 지식이 부족해서 원인을 알 수가 없네요. 😭 어떻게 해결을 하면 좋을까요?  

예제 fashion-mnist-practice 의 모델 생성하는 부분을 참조했습니다. dataset의 경우 fashion_mnist를 쓰지 않고 숫자 mnist 파일을 사용했습니다.  INPUT_SIZE = 28 model = Sequential([     Flatten(input_shape=(INPUT_SIZE, INPUT_SIZE)),     Dense(100, activation='relu'),     Dense(30, activation='relu'),     Dense(10, activation='softmax') ])   이걸 기본으로 model을 따로 저장했고, 저장된 model을 불러오고 별로도 이미지 파일을 만들었습니다.  def get_read_image():     image_list =[]     image = cv2.cvtColor(cv2.imread("./image/0_1.png"), cv2.IMREAD_GRAYSCALE)     return image  def get_show_image(image):     plt.imshow(image)     plt.axis("on")     plt.legend() def get_preprocessed_image(image):     image = np.array(image/255.0, dtype=np.float32)     return image   if __name__ == "__main__":     image = get_read_image()     image = np.resize(image, (1, 784))     image = get_preprocessed_image(image)     image = image.reshape(1, 28, 28, 1)         predict_result = np.argmax(model.predict(image))     print(predict_result)     이렇게 코드를 작성했는데 하나 이해가 가지 않는 부분이 Faltten() 에서 input_shape = IMAGE_SIZE (28), IMAGE_SIZE(28) 이부분입니다. input _shape(28, 28) 로 했다면 업로드한 이미지 파일도 3차원  image.reshape(28, 28, 1)이 들어가야 하는 것 같은데.. 무조건 3차원 만들어줘야 하는 거 아닌가요ㅠ  그래서 그렇게 입력하니깐 오류가 떠서, (1, 28, 28,1)로 넣으니깐 오류가 나지 않습니다. 저 부분이 왜 저렇게 되는지 잘 이해가 가지 않아서 질문 드립니다. 그리고 또 하나는 .   model.summary() 를 했을 때 output shape에 None는 크게 신경쓰지 않아도 되는 것 인가요? 아래 이미지 처럼 (None, 28, 28)이 나왔다면 그냥 28행 28열로 구성된 tensor라고만 생각하면 되는 걸까요 질문이 길어서 죄송합니다 ㅠ input_1 (InputLayer) [(None, 28, 28)] 0 flatten (Flatten) (None, 784) 0 dense (Dense) (None, 100) 78500 dense_1 (Dense) (None, 30) 3030 output (Dense) (None, 10) 310

지금 강의는 아닌데 너무 헷갈리는 부분이있어서요 ㅠㅠㅠ 죄송합니다.   entity가 있고 dto가 있으면 dto -> entitiy로 변환해야되잖아요 그래서 빌더 패턴으로 toenetity메서드를 만들고 이렇게 썼거든요 이게 맞는지요?   근데 다른건 이렇게 생성자를 만들어서 하는게 있는데   둘다 빌더에서 -> 생성자로 변경이 가능하고 빌더에서 -> 생성자로 변경이 가능한건가요? 그냥 선택인 부분인건가요? 그리고 아래List를 빌더로할려고하면 어떻게 해야되는지 궁금합니다 ㅠㅠㅠㅠ

private List<AddressEntity> 에서  왜 @joincolumn(name="member_id")여기에 joincolumn이 썼는지하고 member_id가있는지 모르겠습니다 원래 addressentity에 써져있어야되는거아닌지하고요 연관관계의 주인때문에요 

package hello.core.singleton; public class SingletonService { private static SingletonService singletonService=new SingletonService(); public static SingletonService getInstance(){ return singletonService; } private SingletonService(){ //System.out.println(singletonService); } }  System.out.println(singletonService); // 이 부분이요 !!!!  자바가 뜰때 -> 자동으로 내부적으로 객체 생성해서 -> 참조값이 instance에 들어간다는 이해했습니다. 그래서 생성자에 출력문을 써서 값을 확인해보니 null로 뜹니다 !! 왜 그럴까요??

안녕하세요. 강의 잘 듣고 있습니다.  AAA인증 단계 교육 듣고 있는데요. 강의와 함께 실습을 따라해보던 중 PC쪽에서는 서버까지 핑이 잘 나가는데 반대로 서버쪽에서는 PC쪽으로 핑이 안나가는데요. 서버/라우터1/라우터2 쪽에서 AP까지의 핑이 막힙니다. 이게 정상인지 궁금하구요.. 만약 그렇다면 그 이유가 궁급합니다.
