+## 📋 기능 요구 사항
+
+> 간단한 로또 발매기를 구현한다.
+
+- 로또 번호의 숫자 범위는 1~45까지이다.
+- 1개의 로또를 발행할 때 중복되지 않는 6개의 숫자를 뽑는다.
+- 당첨 번호 추첨 시 중복되지 않는 숫자 6개와 보너스 번호 1개를 뽑는다.
+- 당첨은 1등부터 5등까지 있다. 당첨 기준과 금액은 아래와 같다.
+  - 1등: 6개 번호 일치 / 2,000,000,000원
+  - 2등: 5개 번호 + 보너스 번호 일치 / 30,000,000원
+  - 3등: 5개 번호 일치 / 1,500,000원
+  - 4등: 4개 번호 일치 / 50,000원
+  - 5등: 3개 번호 일치 / 5,000원
+- 로또 구입 금액을 입력하면 구입 금액에 해당하는 만큼 로또를 발행해야 한다.
+- 로또 1장의 가격은 1,000원이다.
+- 당첨 번호와 보너스 번호를 입력받는다.
+- 사용자가 구매한 로또 번호와 당첨 번호를 비교하여 당첨 내역 및 수익률을 출력하고 로또 게임을 종료한다.
+- 사용자가 잘못된 값을 입력할 경우 IllegalArgumentException을 발생시키고, "[ERROR]"로 시작하는 에러 메시지를 출력 후 그 부분부터 입력을 다시 받는다.
+  - Exception이 아닌 IllegalArgumentException, IllegalStateException 등과 같은 명확한 유형을 처리한다.
+
+## 🛠️ 프로그래밍 요구 사항 1
+- **JDK 21** 버전에서 실행 가능해야 한다.
+- 프로그램 실행의 시작점은 Application의 main()이다.
+- **build.gradle** 파일은 변경할 수 없으며, 제공된 라이브러리 이외의 외부 라이브러리는 사용하지 않는다.
+- 프로그램 종료 시 System.exit()를 호출하지 않는다.
+- 프로그래밍 요구 사항에서 달리 명시하지 않는 한 파일, 패키지 등의 이름을 바꾸거나 이동하지 않는다.
+- 자바 코드 컨벤션을 지키면서 프로그래밍한다.
+- 기본적으로 [Java Style Guide](https://github.com/woowacourse/woowacourse-docs/tree/main/styleguide/java)를 원칙으로 한다.
+
+## 📝 프로그래밍 요구 사항 2
+- **indent**(인덴트, 들여쓰기) **depth**를 3이 넘지 않도록 구현한다. **2**까지만 허용한다.
+  - 예를 들어 while문 안에 if문이 있으면 들여쓰기는 2이다.
+  - 힌트: indent(인덴트, 들여쓰기) depth를 줄이는 좋은 방법은 함수(또는 메서드)를 분리하면 된다.
+- **3항 연산자**를 쓰지 않는다.
+- 함수(또는 메서드)가 **한 가지** 일만 하도록 최대한 작게 만들어라.
+- `JUnit 5`와 `AssertJ`를 이용하여 정리한 기능 목록이 정상적으로 작동하는지 테스트 코드로 확인한다.
+
+## 🔍 프로그래밍 요구 사항 3
+- 함수(또는 메서드)의 길이가 **15 라인**을 넘어가지 않도록 구현한다.
+  - 함수(또는 메서드)가 **한 가지** 일만 잘 하도록 구현한다.
+- **else 예약어**를 쓰지 않는다.
+  - else를 쓰지 말라고 하니 switch/case로 구현하는 경우가 있는데 **switch/case**도 허용하지 않는다.
+  - 힌트: if 조건절에서 값을 return하는 방식으로 구현하면 else를 사용하지 않아도 된다.
+- **Java** `Enum`을 적용하여 프로그램을 구현한다.
+- 구현한 기능에 대한 단위 테스트를 작성한다. 단, UI(System.out, System.in, Scanner) 로직은 제외한다.
+  - 단위 테스트 작성이 익숙하지 않다면 `LottoTest`를 참고하여 학습한 후 테스트를 작성한다.
+
+## 🚀 구현할 기능 목록
+
+### 1. 입력 처리
+- [ ] 사용자가 구입할 로또의 총 금액을 **1,000 단위**로 입력
+- [ ] 당첨 번호인 6개의 숫자 입력 (번호는 쉼표(,)로 구분)
+- [ ] 보너스 번호인 1개의 숫자 입력
+
+### 2. 로또 번호 생성
+- [ ] 사용자가 구매한 금액에 따라 해당 수량만큼 로또 번호 생성
+- [ ] 1부터 45까지의 숫자 중 중복되지 않는 6개의 로또 번호를 랜덤하게 생성
+
+### 3. 당첨 번호 저장
+- [ ] 입력받은 당첨 번호 및 보너스 번호 리스트 생성
+
+### 4. 당첨 결과 및 수익률 계산
+- [ ] 구매한 로또 번호와 당첨 번호를 비교하여 일치하는 개수 계산
+- [ ] 각 등수별 당첨 금액으로 총 수익을 계산
+- [ ] 계산된 수익과 구입한 로또의 총 금액을 기반으로 소수점 둘째 자리에서 반올림하여 수익률 계산
+
+### 5. 출력 처리
+- [ ] 사용자가 구매한 로또의 개수와 랜덤 번호 오름차순 출력
+- [ ] 등수별 당첨 개수와 해당 상금 출력
+- [ ] 당첨 금액과 총 수익률 출력
+
+### 6. 예외 처리
+- [ ] 구입 금액이 1,000의 배수가 아닐 시
+- [ ] 구입 금액이 100,000원을 초과할 시 (구입한 로또 개수가 100개를 초과할 시)
+- [ ] 로또 구매 개수가 1개 이하일 시
+- [ ] 당첨 번호의 구분자로 쉼표(,)를 사용하지 않을 시
+- [ ] 당첨 번호가 중복되거나 보너스 번호가 당첨 번호와 중복될 시
+- [ ] 당첨 번호와 보너스 번호가 1부터 45 사이의 범위를 벗어날 시
+- [ ] 당첨 번호 6개, 보너스 번호 1개의 개수에서 벗어날 시
+- [ ] 입력된 값의 형식이 숫자가 아닐 시 (단, 당첨 번호 입력에서 구분자는 허용함)
+- [ ] 입력된 값이 공백 또는 빈 문자열일 시
+
+### 7. 테스트
+- [ ] **기능 단위 테스트**로 프로그램의 비즈니스 로직이 올바르게 작동하는지 검증
+- [ ] **예외 단위 테스트**로 프로그램이 예외 상황에 적절한 에러 메시지를 출력하는지 검증
+
+## 🎯 3주차 과제의 목표
+2주차의 코드 리뷰를 상기하며 피드백에 따라 코드를 작성하기
+
+1. if문 내에서 중괄호를 생략하면 안 됨 (`Google Java Style Guide` 어긋남)
+2. 메서드 네이밍 중 `is`가 접두어로 쓰이면 `boolean` 타입을 반환할 것 같으니 메서드명을 명확하게 표현하자
+3. 하드 코딩 대신 범위나 조건 값을 상수로 처리해 일관성 가지기 (2주차 공통 피드백과 일맥상통)
+4. 예외에 대한 테스트뿐만 아니라 도메인 로직에 대한 테스트 코드 추가하자
+5. `String` 클래스 메서드와 같은 함수를 활용해 코드의 가독성을 높이자
