자바 쓰레드 화장실 예제

한사람당 꼭 하나의 쓰레드만 작동을 알 수 있는 좋은 예입니다.

public class Toilet {
 public synchronized void openDoor(String name){
  System.out.println(name);
  usingTime();
  System.out.println("아~~시원해");
 }
 public void usingTime(){
  for(int i=0; i<1000000; i++){
   if(i==10000)
    System.out.println("끄으응~~");
  }
 }
}

class Familly extends Thread{
 Toilet toilet;
 String who;
 
 Familly(String name, Toilet t){
  who = name;
  toilet = t;
 }
 public void run(){
  toilet.openDoor(who);
 }
}
class ToiletTest{
 public static void main(String[] args) {
  Toilet t = new Toilet();
 
  Familly father = new Familly("아버지", t);
  Familly mother = new Familly("어머니", t);
  Familly sister = new Familly("누나", t);
  Familly brother = new Familly("형", t);
  Familly me = new Familly("나", t);
 
  father.start();
  mother.start();
  sister.start();
  brother.start();
  me.start();
 }
}
