양식 (보기)에서 사용자 입력을 가져 와서 데이터베이스에 삽입하는 두 가지 종류의 필드에서 제출을 수행해야하는데 이미 검색을 시도하고 무언가를 찾으려고했습니다. 그물과 내가 본 모든 것은 자동으로 PC로부터 날짜와 시간을 삽입하는 코드 였지만, 사용자가 입력 한 데이터를 삽입하고 싶습니다. 다음과 같이하려고합니다 :날짜 및 시간 형식을 입력하는 방법

} 그래서 나는 모든 방법하지만 스택 트레이스 예외를 시도했습니다
내가하시기 바랍니다 데이터베이스의 사용자 날짜와 시간 입력을 허용하는 코드를 할 어떤 조언을 알고 싶습니다! 고마워요 !!
왜 java.util.Date가 왜 java.sql.date를 사용하고 사용하지 않는에 반환 형식으로 된 다음 개체가되었다? 특별한 요구 사항이 있습니까? – Irakli
이 예외가 발생하는 위치에 대해 구체적으로 설명하십시오. 전체 스택 추적을 게시하고 예외 위치를 나타냅니다. 우리는'java.util.Date'를'java.sql.Date'에 던져 넣으려는 곳을 찾기 위해 코드의 벽을 살펴 보려고하지 않습니다. –
@JONIVar 그는 JDBC를 사용하면서 결국에는 java.sql.Date (또는 java.sql.Timestamp)를 필요로합니다. –
