Java 행맨 프로그램

Question

내 코드에서 다음과 같은 오류를 찾아내는 데 도움이 필요합니다. 사용자가 신비 단어에 입력 한 올바른 자를 바꿉니다. 내 마지막 메서드의 기능은이 작업을 수행하는 것입니다. 그러나 올바른 문자 하나만 입력하고 올바른 추측을 모두 입력하는 이유는 알 수 없습니다. 또한 사용자가 시도 할 수있는 최대 시도 횟수는 8이지만 프로그램을 컴파일 할 때 시도 횟수가 음수로 바뀌고 최대 시도 횟수에 문제가 있음을 알 수 없습니다. 미리 감사드립니다! 정말 고마워. ** 또한이 프로그램에서 여러 가지 방법을 사용하는 것은 과제에 대한 요구 사항입니다!

논리가 거꾸로입니다. 시도는 다음 -1 인 경우 : 즉

while(... || (guess.equals(word) && (tries < 8) && (tries > 0)) { 
while(... || (guess.equals(word) && (-1 < 8) && (-1 > 0)) { 
while(... || (guess.equals(word) && true && false)) { 
while(... || !(false)) { 
while(... || true) { 
while(true) { 

tries 검사가 잘못이기 때문에, 루프는 종료 할 수 없다.

while (!guess.equals(word) && (tries > 0)) { 

입니다.
