netbeans에서 만든 프로젝트가 있는데, 컴파일 할 때 클래스 파일을 만들었습니다. 하지만 컴파일 후에 operator.java라는 파일이 있으면 operator.class, $ 1.class 연산자, $ 2.class 연산자 등이 있습니다. 특별한 이유가 있습니까? 왜 그런지 설명해 주시겠습니까?Netbeans는 컴파일시에 의문이 생깁니다.

위의 코드에서 나는 6 클래스를 얻었습니다. 그래서 여러분은이 코드를 작성하는 책임이있는 선을 선택합니다. oz이 코드에서 내부 클래스를 사용하지 않습니다. 나는 Enum 개념에 대해 확신하지 못한다. 당신이 나를 도울 수 있다면 거기서부터 배우기 시작할 수있다. ..
나 한테 더 설명해 줄 수 있어요? ? 내 편집을 확인하십시오 .. – Deepak
@Deepak : 설명을 추가했습니다 –
