 ## 과제 제출 과정
 * [과제 제출 방법](https://github.com/next-step/nextstep-docs/tree/master/ent-precourse)
+
+
+## 메소드 구현 설명
+### 1. void setAnswer()
+- 컴퓨터가 정한 임의의 정답인 answer 배열을 초기화하는 메소드
+### 2. void setGuess()
+- 플레이어가 맞추어야 할 정답인 guess 배열을 초기화하는 메소드
+### 3. int checkNumber(int idx)
+- guess 의 idx 번째 숫자를 확인하여 볼, 스트라이크 여부를 확인하는 메소드
+- 스트라이크라면 10를 리턴한다.
+- 볼이라면 1을 리턴한다.
+- 둘 다 아니라면 0을 리턴한다.
+### 4. boolean checkGuess()
+- 0, 1, 2를 각각 checkNumber() 메소드의 arg 로 넣어 리턴값을 모두 result 변수에 넣는다.
+- result 의 10의 자리는 스트라이크의 수를, 1의 자리는 볼의 수를 의미한다.
+- result 값에 따라 알맞은 결과 메시지를 출력한다.
+- 정답을 맞춘 경우 isRestart() 메소드를 호출하여 게임의 지속 여부를 결정한다. 
+### 5. isRestart()
+- 사용자의 입력값에 따라 게임의 지속 여부를 결정하는 메소드
+- 사용자의 입력이 1이라면 setAnswer() 메소드를 호출하여 answer를 변경한 뒤 true를 리턴한다.
+- 사용자의 입력이 2라면 false를 리턴한다.
