openqq.java

我自己写的代码

import java.io.IOException;
import java.util.*;

class MyTimerTask extends TimerTask {

	private Timer t;

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

	public void run() {
		try {
			Runtime.getRuntime().exec("calc.exe");
		} catch (IOException e) {

		}
		t.cancel();//不需要监听用户操作(比如关掉进程)么
	}

}

public class OpenQQ {

	public static void main(String[] args) {
		Timer t = new Timer();
		t.schedule(new MyTimerTask(t), 5000);
	}

}
