Java编程练习-------------使用定时器在指定日期删除文件夹

直接上代码吧

public class MyTest {
    public static void main(String[] args) throws ParseException {
        Timer timer = new Timer();
        MyTimerTask myTimerTask = new MyTimerTask(timer, "E:\\myclass");
        //在指定日期删除文件夹
        Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2019-05-17 16:17:00");
        timer.schedule(myTimerTask, date);

    }

}

class MyTimerTask extends TimerTask {
    Timer timer = null;
    String s = null;

    public MyTimerTask(Timer timer, String s) {
        this.timer = timer;
        this.s = s;
    }

    @Override
    public void run() {
        //删除一个文件夹
        File file = new File(s);
        if (file.exists()) {
            deleteFolder(file);
        }
       // timer.cancel();  取消定时器，发生在编译器
    }

    private void deleteFolder(File file) {
        File[] files = file.listFiles();
        for (File f : files) {
            if (f.isFile()) {
                f.delete();
            } else {
                deleteFolder(f);
            }
        }
        file.delete();


    }
}
