getDate() 질문이요

Question

안녕하세요. 안드로이드를 혼자 독학으로 공부한지 일주일이 좀 넘었는데

이클립스용 교제를보고 안드로이드스튜디오에서 예제문제를 따라하면서 공부중인데 입력을 똑같이 했는데도

java.util.Date cDate = new java.util.Date(dPicker.getDate()); 자바쪽 이부분에서 getDate()부분이 에러가나는데

왜그런건가요? 그냥..저부분을 아무렇게나 수정해서 에러가 안뜨게 만들어서 실행을 시켜서

예약 시작 버튼이나 예약완료 부분을 누르면 에뮬레이터에서 어플이 종료되버리는데..

혼자 구글링도해보고 해봐도 해결이안되네요..해결방법좀알려주세요.
