자바 구문 오류가 토큰에 잘못 배치 된 구문

Question

메신저 자바 자동 판매기 OS를하고있는 중이며 방금 원래 프로젝트를 이클립스로 가져 와서 사람 페이지를 추가 한 후 오류가있는 곳은 어디에도 던지지 않았습니다. 내가 뭘 도와 드릴까요? 주요 오류는 '토큰에 대한 구문 오류, 잘못 배치 된 구문 (s)'입니다. 코드가 잘못되었거나 스크랩이 비효율적 인 경우 사전에 사과드립니다.

Answer 1

당신은

class OS { 

과 첫 번째가 제거되어야한다 또한

public class OS extends Frame { 

있습니다.

이외의 개체 '슬롯'이 선언되고 초기화되지 않았습니다.

class OS { 

및

slot.d(activate); 

파일의 두 줄을 제거한 후 컴파일하고 실행해야합니다.
