예, 이전에이 질문에 대해 알고 있습니다. 그러나 기능을 수행하는 우리의 방법은 다르므로 이러한 이유로 중복으로 표시해서는 안됩니다.자바 - 계산기 GUI
저는 계산기 GUI 기능을 만들려고합니다. 그러나 현재 사용자가 숫자를 클릭 한 다음 그 번호를 화면에 출력하게해야합니다.
분할 기능 (현재 설정 한 유일한 기능)을 클릭하면 "1"이 화면에 인쇄됩니다. 분명히 사용자의 입력 (클릭 수)이 변경되지 않고 두 번 표시되기 때문에 이것은 오류가 아닙니다. (내가 지금 뭐하는 거지 본질적으로) 그 자체로 나누어 그 숫자는이 내 현재 코드 1.

가 나는 또한 (소수점 기능을 포함시킬 당신이 할 수 있도록 복식 등),하지만 그렇게하는 방법에 관해서는 길을 잃었다. 두 가지 질문에 대한 모든 도움이 크게 감사하겠습니다.
감사합니다.
쉬운 권장 사항 : (1) import 문에 대해 배우고, (2) 루핑 및 배열에 대해 배웁니다. 너무 추악하고 반복적 인 코드는 좋은 것으로 간주됩니다. – duffymo
