timer 的使用

Cancel来把task 停止， schedule来启动

import java.util.Calendar;
import java.util.Timer;
import java.util.TimerTask;
import java.util.concurrent.LinkedBlockingQueue;

public class TimerClient {
	
	static LinkedBlockingQueue<String> words = new LinkedBlockingQueue<String>();
	static{
		System.setProperty("file.encoding","UTF-8");
		words.add("请妹子喝奶茶 ");
		words.add("她问这杯夺钱一杯啊 ");
		words.add("我说12块 ");
		words.add("她摇手说不喝了 口红很贵  ");
		words.add("。。。。。。");
		
	}
	
	public static void main(String[] args) {
		Timer t = new Timer();
		NewTimerTask cr = new NewTimerTask(t);
		
		Calendar cad = Calendar.getInstance();
		cad.add(Calendar.SECOND, 1);
		
		t.schedule(cr, cad.getTime(), 1500);
	
		while(words.size() == 0){
			cr.cancel();
			t.cancel();
			System.exit(0);
		}
	}
	
	public static class NewTimerTask extends TimerTask {
		Timer tm;
		
		public NewTimerTask(Timer tt) {
			tm = tt;
		}
		
		@Override
		public void run() {
			System.out.println(words.poll() );
			if(words.size() == 0) {
				try {
					tm.cancel();
				} catch (Exception e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
			
		}
	}
