간단한 회원관리 GUI SWING 툴

JAVA에서 SWING으로 GUI를 구현할 수 있습니다.
윈도우 툴로서 사용하기 간편합니다.

주로 회원관리 같은경우에는 DB를 이용하여 어플리케이션을 만들어 사용합니다.

허나, 간편하게 나혼자 보거나, 고시원 같은 작은 회원관리 하는 곳에서 간편하게 나만 사용하기에는 DB보다 엑셀이 간편하죠.

간단한 소스 업로드 합니다.
이 소스에서는 SWING을 이요하여 회원의 이름, 전화번호, 나이, 성별, 등급을 입력하면 동일한 aa.csv에 저장합니다.

이 소스를 토대로 편집하여 나만의 툴을 만들어서 사용하시면 간단한 회원관리나 고시원 등의 고객관리 에 사용할 수 있겠습니다

사용한 라이브러리는 csv 하나입니다.

gradle 의 경우 아래와 같이 추가하시면 됩니다
dependencies {
implementation 'com.opencsv:opencsv:5.5.2'

}
직접 라이브러리 다운받아 추가하셔도 됩니다.

다른거 필요없이 코드만 제공됩니다.
