나머지 코드와 정확히 동일한 코드 마지막 부분의 오류

Question

코드 마지막 부분에서 변수 초기화 오류가 발생합니다. 코드의 나머지 부분과 형식이 다르지 않기 때문에 이상하게 느껴집니다. 여러 번 검토 한 결과 문제가 보이지 않습니다. 나는 이것에 대해 또 다른 시각이 필요하다고 생각한다.

아이디어 누구?

    } 
    else

    else

    System.out.println("You want " + message); 
    System.out.println("You want " + message2);

    System.out.println("You want " + message4); 
    System.out.println("You will have " + choice); 
    System.out.println("You will have " + choice2);

}

@OpiesDad가 지적했듯이 최종 블록의 변수 이름이 일치하지 않습니다.

또한 내게 가장 먼저 튀어 나온 점은 각 if-then-else 블록에서 마지막 else 블록 주위에 대괄호가 누락되어 해당 메시지 변수가 항상 "유효하지 않음"으로 설정된다는 것입니다 선택권".

과 같아야 다른 마지막 :

else 
{ 
    choice = "invalid"; 
    message = "An invalid option"; 
}
