Java 如何在“时间”中指定时间；每周五凌晨1点；以毫秒为单位，用于cron作业？

嗨，我想写一个课程来安排在特定时间的工作。这是密码

public void test(){
        Timer timer = new Timer();
        Calendar date = Calendar.getInstance();
        date.set(Calendar.HOUR,0);
        date.set(Calendar.MINUTE, 0);
        date.set(Calendar.SECOND, 2);
        date.set(Calendar.MILLISECOND,0);

        //schedule to run on 1 am every friday. 
        timer.schedule(new JobRunner(), date.getTime(),1*0*0*0);
    }

请在最后一行提供帮助，我不知道如何在那里指定时间

谢谢

我希望这能有所帮助

    static final long period = 7*24*60*60*1000;//one week

public void test(){
    Timer timer = new Timer();
    Calendar date = Calendar.getInstance();
    date.set(Calendar.HOUR_OF_DAY, 1);
    date.set(Calendar.MINUTE, 0);
    date.set(Calendar.SECOND, 0);
    date.set(Calendar.MILLISECOND,0);
    date.set(Calendar.DAY_OF_WEEK, Calendar.FRIDAY);
    //in case you run the batch before date
    if (date.before(Calendar.getInstance())) {
        date.add(Calendar.DAY_OF_YEAR, 7);
    }        

    long delay =  date.getTimeInMillis() - new Date().getTime();              
    //schedule to run on 1 am every friday. 
    timer.schedule(new JobRunner(), delay, period);              
}
