java定时器练习

• 交互实现两秒和四秒显示爆炸

public class Timer01 {    private static int count=0;    public static void main(String[] args) {    //定时器实例一次只能实现一次操作，所以需要写个继承于TimerTask的类来不断实例         class MyTimer extends TimerTask{                @Override                public void run() {                    count=(count+1)%2;                    System.out.println("爆炸");                    new Timer().schedule(new MyTimer(),2000+2000*count);                            }            }        new Timer().schedule(new MyTimer(), 2000);        //通过线程休眠显示秒数    while (true) {            System.out.println(new Date().getSeconds());            try {                Thread.sleep(1000);            } catch (InterruptedException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }           }    }}
