그래서 화면을 클릭하면 간단한 프로그램을 만들려고합니다. 아래쪽에있는 더 큰 블록과 충돌하여 블록을 만듭니다. 일종의 단순 충돌 프로그램 같아. 문제는 이전에 블록을 삭제 한 블록을 만들 때입니다. 배열을 만들었지 만 여전히이 작업을 수행합니다. 임씨가 잘못한 것을 당신이 알고 있습니까? 확실히 그것의 간단한 수정.여러 사각형을 그리는 방법

제안한 코드를 추가했으며 위의 편집. 그것은 여전히 한 번에 한 블록 씩 그립니다. 나는 무엇을 잘못 할 수 있 었는가? –
Opps, 나는'mouseReleased' 코드에서 실수를했고'paintComponent' 루프를 업데이트했습니다. – MadProgrammer
알았어요! 고마워요! –
