java.lang.NumberFormatException을 해결하는 방법 : 입력 문자열이

Question

이니 지금 당분간이 프로젝트를 진행하고 있습니다. 최근에이 문제가 발생했습니다.

매번 앱은 잘 컴파일하지만 응용 프로그램은이 시작 갈 때 나는 세부 사항 버튼을 누를 때 그것은 나에게이 있습니다 :

답변 해 주셔서 감사합니다.

Answer 1

코드가 없으므로 확실하게 말할 수는 없지만 파일이 아닌 문자열을 전달하는 것이 문제라고 가정합니다. 예를 들어, 당신은 할 수 있습니다

("\ProyectoOUMA\ouma.administracfdi.Reader\dist"); 

당신이해야 할 때 :

(new File("\ProyectoOUMA\ouma.administracfdi.Reader\dist")); 

를이 방법으로 문제가 해결되지 않으면, 당신의 코드를 볼 수 있는지 다시 검토해 드리겠습니다.
