100张票，10个窗口（10个线程模拟），实现线程卖票计数




import java.util.Iterator;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

public class SellTicket implements Runnable {
	
	private int count = 100;
	static Map<String,Integer> map = new ConcurrentHashMap<String,Integer>(); 
	
	public static void main(String[] args) {	
		SellTicket st = new SellTicket();
		for (int i = 0; i < 10; i++) {
			Thread thread = new Thread(st);
			map.put(thread.getName(), 0);
			thread.start();
		}
	}

	@Override
	public void run() {
		while (true) {
			synchronized(this){
				if(count > 0){
					count--;
					System.out.println("线程=" + Thread.currentThread().getName() + "；剩余票数=" + count);					
					Iterator<Map.Entry<String,Integer>> i = map.entrySet().iterator();
					while(i.hasNext()){
						Map.Entry<String,Integer> entry=(Map.Entry<String,Integer>)i.next();
						if(entry.getKey().equals(Thread.currentThread().getName()))
							map.put(entry.getKey(), entry.getValue().intValue() + 1);
					}					
				}else if(count==0){					
					Iterator<Map.Entry<String,Integer>> i = map.entrySet().iterator();
					while(i.hasNext()){
						Map.Entry<String,Integer> entry=(Map.Entry<String,Integer>)i.next();
						System.out.println("线程=" + entry.getKey() + "；卖票数=" + entry.getValue());
					}		
				}
			}
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}

}
