## 질문 각 줄의 온도를 읽어 온도차를 계산한 결과를 출력해줘야 합니다. (문제의 조건, 제가 작성한 코드, 그리고 결과(오류) 순으로 스크린샷 첨부해두었습니다.) 이클립스에서 실행했을경우 문제가 없었는데 해당 사이트에 제출하려고만 하면 저런 오류가 발생하는데 이유를 잘 모르겠습니다. 해결방법을 여쭙고자 합니다! ## 입력 파일 내용 ``` 16.2 23.2 19.2 7.7 22.9 18.4 -1.6 14.6 ``` ![enter image description here][1] ## 실행 예 ``` Input file? weather.txt 16.2 to 23.2, change = 7.0 23.2 to 19.2, change = -4.0 19.2 to 7.7, change = -11.5 7.7 to 22.9, change = 15.2 22.9 to 18.4, change = -4.5 18.4 to -1.6, change = -20.0 -1.6 to 14.6, change = 16.2 ``` ![enter image description here][2] ## 작성 코드 ``` public class Weather extends ConsoleProgram { public void run() { String file = promptUserForFile("Input file?
