上一篇博客当中，利用栈对Timer和TimerTask进行了封装，在实际运用的当中觉得很好用，这次增加了运行过程中的状态信息。

具体代码如下所示：

public class MyTimer {    private MyTimerTask task;    private int date;    private long period;    private Stack
     
       taskStack;    private Timer timer;    private int state;    public static int READY = 0;    public static int RUNNING = 1;    public static int PAUSE = 2;    public static int STOP = 3;    public MyTimer(TimerTask timerTask, int date, int period){        task=new MyTimerTask(timerTask);        this.date=date;        this.period=period;        timer=new Timer();        taskStack=new Stack
      
       ();        state = READY ;    }    public void start() {        if(state == READY){//准备状态            timer.schedule(task, date, period);        }else if(state == PAUSE){//暂停状态            resume();        }else{            return ;        }        state = RUNNING ;    }    public void stop() {        try {            timer.cancel();            taskStack.clear();            task.cancel();        }catch(Exception e){            e.printStackTrace();        }        state = STOP;    }    public void pause() {        if(state == RUNNING) {            //使用栈保存当前的任务            taskStack.push(new MyTimerTask(task.getCurrentTask()));            task.cancel();            state = PAUSE;        }    }    private void resume() {        try {            //出栈，恢复保存的任务            task = taskStack.pop();            timer.schedule(task, 0, period);        }catch(Exception e){            e.printStackTrace();        }    }    public int getState(){        return this.state;    }    private class MyTimerTask extends TimerTask{        private TimerTask task;        public MyTimerTask(TimerTask task){            this.task=task;        }        @Override        public void run() {            task.run();        }        public TimerTask getCurrentTask(){            return task;        }    }}
