| 150923 쓰레드 윈도우 프로그래밍
****Thread - 한 작업
1) processs program 파일이 저장만 되어있으면 프로그램, 실행이 되면 프로세스
2) 단일 프로세스 멀티프로세스
3) 하나의 프로세스 에서 실횅하는 작업 단위
4) 멀티쓰레드 -
5) 모든프로그램은 반드시 하나이상의 쓰레드를 포함
-main():메인쓰레드
6) 스레드 구현방식
1. runnable
2. Thread 클래스
7) LifeCycle
8) 동기화 (Synchronize)
1) 세마포어 ,뮤텍스
2) synchronized
- 메서드 에서만 사용
- block 사용
synchronized (객체주소){
코드...
}
9) 스레드의 종료
1) 우선순위 (메인스레드가 가장 나중에 종료할 수 있도록 유도 )
- isAlive()
- join()
2) 종료방법 ( 강제 종료를 해야 할 경우 )
- stop() // 전선 뽑는 급의 종료, 왠만하면 쓰지말아야할 메소드
- inturrupt() // stop 보다는 부드러운 종료
- 직접종료 // 직접 내손으로처리함

windows programming
윈도우 프로그래밍
1. AWT (Abstract Window Toolkit ) -> Swing
2. 3요소
1) 재료 : component
- java.awt 패키지
- Button, Canvas, Checkbox, Choice, Container, Label, List,
-container
panel
Applet
winldows
Dialog
Frame (크기 를 정하고 보여줄 수 있게 설정 )
dialog common dialog(내장 다이얼로그, 시스템 다이얼로그)
user Definedialog ( dialog를 상속 )
Modal 과Modaless
2) 디자인 (배치) : LayOut
- 재료(component)를 원하는 위치에 배치
-레이아웃 매니저
FlowLayout
: 순서대로
: 패널
BorderLayout
: 테두리를 기준으로 배치 (동, 서, 남, 북, 중)
: window 의 기본 레이아웃
GridLayout
: 테이블 모양으로 배치
GridBagLayout
: 불규칙 테이블 모양으로 배치
CardLayout
: 보더레이아웃 처럼 배치를 해놓고 화면전환용 으로 이용가능
3) 동작 : Event
3. 분야
1)어플리케이션
2) 애플릿
