import java.util.TimerTask;

public class Timer_run {
	public static void main(String[] args) {
		Timer t=new Timer();
		//3秒开始
		t.schedule(new MyTimerTask(t), 3000);

	}

}
class MyTimerTask extends TimerTask{


	private Timer t;
	public MyTimerTask(Timer t){
		this.t=t;

	public void run() {
		System.out.println("beng,爆炸了");
		t.cancel();
