+### 로또 발매기
+
+간단한 로또 발매기를 구현한다.
+
+### 구현할 기능 목록
+
+**프로그램 실행 시**
+
+- 로또 구입 금액을 입력 받는다. 구입 금액은 1,000원 단위로 입력 받는다
+- 당첨 번호를 입력 받는다. 번호는 쉼표(,)를 기준으로 구분한다
+- 보너스 번호를 입력 받는다
+
+**출력**
+
+- 발행한 로또 수량 및 번호를 출력한다
+- 로또 번호는 오름차순으로 정렬하여 보여준다
+- 당첨 내역을 출력한다
+- 수익률은 소수점 둘째 자리에서 반올림한다
+
+**예외 처리**
+
+- 구입 금액이 숫자가 아닌 경우 예외 처리한다
+- 구입 금액이 0원인 경우 예외 처리한다
+- 로또 구입 금액이 1,000원으로 나누어 떨어지지 않는 경우 예외 처리한다
+- 로또 당첨 번호가 중복인 경우 예외 처리한다
+- 로또 당첨 번호의 개수가 6개 초과일 경우 예외 처리한다
+- 로또 번호가 1~45 사이의 숫자가 아닌 경우 예외 처리한다
