가위바위보 게임 프로그램

**가위 바위 보를 0,1,2 숫자로 나타내어 

컴퓨터와 게임했을 때 이기고 지고 비길때의 규칙을 찾아내는 것이 관건

 

**게임 패키지 따로 생성 후 작성

view

JFrame으로 상속, 액션 리스너 상속 (그냥 label은 한글깨짐 발생, swing계열은 한글깨짐 없음(JLabel))

 

label이 많이 필요하므로 배열로 생성
JLabel label[];
button[]도 배열. list로 잡아도 되나 추가삭제할 필요업으므로 일반 배열

 

frontlabel셋팅-> 게임제목 설정(?승?패?무)

 

label 배열길이 5,
{사용자이름, 컴퓨터이름, 사용자 결과, 승패 출력, 컴퓨터 결과}

 

button  배열길이 3
{가위, 바위, 보}
for문은로 각 버튼을 변수에 입력받아 위치셋팅

변수 int로 승 패 무;-> getter 생성

init에서 랜텀 초기화, 

유저넘버는 밖에서 들어오므로 -> setter
play에서 판정
 if 문으로 하면 너무 길어짐.

 

((comNum - userNum)+2)%3 => 1일경우 win = result;
((comNum - userNum)+2)%3 => 0일경우 lose
((comNum - userNum)+2)%3 => 2일경우 draw
-> 스위치문사용하면 간결
case1: win++; msg에 메세지 입력;
 retrun msg;
