행맨 게임에서 파일을 읽을 수 없음

Question

이 프로그램은 .txt 파일에서 임의의 단어를 선택하고 사용자가 단어에 대한 문자를 추측 해보라고합니다. 그것은 실행되지만, 모든 단어에있는 편지라는 것을 알고있을 때에도 항상 "단어는 발견되지 않았습니다"라고 말합니다. 이것은 내가 .txt 파일을 제대로 읽지 못한다고 생각하게 만듭니다.

결코 예외를 포착하고 예외를 무시하지 마십시오! 이 같은 프로그램의 상단에있는 캐치 절을 변경 :

catch (FileNotFoundException e) { 
    e.printStackTrace(); 
} 

을 그래서 당신은 당신의 단어 목록을 읽는 동안 나쁜 일이 일어난 경우 적어도 힌트를 가질 것이다.

이것은 굵은 글씨로 반복되는 중요한 교훈입니다. 결코 예외를 포착하고 무시하지 마십시오!
