-# 과제 - 로또
-
-## 🔍 진행 방식
-
-- 과제는 **기능 요구 사항, 프로그래밍 요구 사항, 과제 진행 요구 사항** 세 가지로 구성되어 있다.
-- 세 개의 요구 사항을 만족하기 위해 노력한다. 특히 기능을 구현하기 전에 기능 목록을 만들고, 기능 단위로 커밋 하는 방식으로 진행한다.
-- 기능 요구 사항에 기재되지 않은 내용은 스스로 판단하여 구현한다.
-
----
-
-## 📈 과제 진행 및 제출 방법
-
-- 과제는 [java-lotto](https://github.com/LandvibeDev/java-lotto) 저장소를 Fork/Clone해 시작한다.
-- **기능을 구현하기 전에 java-baseball-precourse/README.md 파일에 구현할 기능 목록을 정리**해 추가한다.
-- **Git의 커밋 단위는 앞 단계에서 README.md 파일에 정리한 기능 목록 단위**로 추가한다.
-  - [AngularJS Commit Message Conventions](https://gist.github.com/stephenparish/9941e89d80e2bc58a153) 참고해 commit log를 남긴다.
-- 과제 진행 및 제출 방법은 [우아한코스 과제 제출 문서](https://github.com/woowacourse/woowacourse-docs/tree/master/precourse) 를 참고한다.
-  - base repository를 `LandvibeDev/java-lotto`로 지정해서 PR 생성하면됨

-### 테스트 실행 가이드
-
-- 터미널에서 `java -version`을 실행하여 Java 버전이 14인지 확인한다. 또는 Eclipse 또는 IntelliJ IDEA와 같은 IDE에서 Java 14로 실행되는지 확인한다.
-- 터미널에서 Mac 또는 Linux 사용자의 경우 `./gradlew clean test` 명령을 실행 하고,   
-  Windows 사용자의 경우  `gradlew.bat clean test` 명령을 실행할 때 동작 하는지 만 확인(테스트는 실패).

-## 🎯 프로그래밍 요구 사항
-
-- JDK 14 버전에서 실행 가능해야 한다.
-- 프로그램 실행의 시작점은 `Application`의 `main()`이다.
-- `build.gradle` 파일을 변경할 수 없고, 외부 라이브러리를 사용하지 않는다.
-- [Java 코드 컨벤션](https://naver.github.io/hackday-conventions-java/) 가이드를 준수하며 프로그래밍한다.
-- 프로그램 종료 시 `System.exit()`를 호출하지 않는다.
-- 프로그램 구현이 완료되면 `ApplicationTest`의 모든 테스트가 성공해야 한다.
-- 프로그래밍 요구 사항에서 달리 명시하지 않는 한 파일, 패키지 이름을 수정하거나 이동하지 않는다.
-- indent(인덴트, 들여쓰기) depth를 3이 넘지 않도록 구현한다. 2까지만 허용한다.
-    - 예를 들어 while문 안에 if문이 있으면 들여쓰기는 2이다.
-    - 힌트: indent(인덴트, 들여쓰기) depth를 줄이는 좋은 방법은 함수(또는 메서드)를 분리하면 된다.
-- 3항 연산자를 쓰지 않는다.
-- 함수(또는 메서드)가 한 가지 일만 하도록 최대한 작게 만들어라.
-- JUnit 5와 AssertJ를 이용하여 본인이 정리한 기능 목록이 정상 동작함을 테스트 코드로 확인한다.
-- 함수(또는 메서드)의 길이가 15라인을 넘어가지 않도록 구현한다.
-    - 함수(또는 메서드)가 한 가지 일만 잘 하도록 구현한다.
-- else 예약어를 쓰지 않는다.
-    - 힌트: if 조건절에서 값을 return하는 방식으로 구현하면 else를 사용하지 않아도 된다.
-    - else를 쓰지 말라고 하니 switch/case로 구현하는 경우가 있는데 switch/case도 허용하지 않는다.
-- Java Enum을 적용한다.
-- 도메인 로직에 단위 테스트를 구현해야 한다. 단, UI(System.out, System.in, Scanner) 로직은 제외한다.
-    - 핵심 로직을 구현하는 코드와 UI를 담당하는 로직을 분리해 구현한다.
-
-### 라이브러리
-
-- [`camp.nextstep.edu.missionutils`](https://github.com/woowacourse-projects/mission-utils)에서 제공하는 `Randoms` 및 `Console` API를 사용하여 구현해야 한다.
-    - Random 값 추출은 `camp.nextstep.edu.missionutils.Randoms`의 `pickUniqueNumbersInRange()`를 활용한다.
-    - 사용자가 입력하는 값은 `camp.nextstep.edu.missionutils.Console`의 `readLine()`을 활용한다.
-
-#### 사용 예시
-
-```java
-List<Integer> numbers = Randoms.pickUniqueNumbersInRange(1, 45, 6);
-```
+### 기능 구현
+
+1. 구입 금액 입력받기
+   - 1000으로 나누어 떨어지지 않는값 입력시 `IllegalArgumentException`를 발생시키고, "[ERROR]"로 시작하는 에러 메시지를 출력 후 종료
+2. 로또 생성
+   - 1~45 범위의 중복되지 않는 6개의 숫자
+   - pickUniqueNumbersInRange 사용
+3. 로또 숫자 각각 출력
+   - 오름차순으로 형식에 맞게 
+4. 당첨 번호 입력받기
+   - 1~45 범위의 중복되지 않는 6개의 숫자
+   - ',' 를 기준으로 구분
+5. 보너스 번호 입력
+   - 1~45 범위의 기존 로또값에 중복되지 않는 1개의 숫자
+6. 당첨 통계 출력
+   - 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
+7. 총 수익률 계산
