从明天和两个月前一整天，绕过他们 [英] Get all days from tomorrow and two months forward and loop through them

问题描述

我明天要带走，加上60天，并逐日循环。只是想知道这样做的适当方式是什么？

I need to take tomorrow, add 60 days to it and loop over it day by day. Just wondering what would be the appropriate way of doing this?

这是我尝试的

    Calendar startCalemder = Calendar.getInstance();
    startCalemder.setTime(new Date());
    startCalemder.add(Calendar.DATE, 1);

    Calendar endCalendar = Calendar.getInstance();
    endCalendar.setTime(new Date());
    endCalendar.add(Calendar.DATE, 60);

    //loop over day by day
    for (; startCalemder.compareTo(endCalendar) <= 0;
            startCalemder.add(Calendar.DATE, 1)) {
        startCalemder.get(Calendar.YEAR); //shows year
        startCalemder.get(Calendar.MONTH); //shows month
        startCalemder.get(Calendar.DAY_OF_MONTH); //shows day
    }

推荐答案

这样做：

public static void main(String[] args) {
    final Calendar c = Calendar.getInstance();

    //set the timestamp info to 00:00:00 so that we can compare the dates later if needed
    c.set(Calendar.HOUR_OF_DAY, 0);
    c.set(Calendar.MINUTE, 0);
    c.set(Calendar.SECOND, 0);
    c.set(Calendar.MILLISECOND, 0);

    final int days = 61; //61 because we will add the result after we add the day

    final List<Date> datesList= new ArrayList<Date>(); //list to store each date object

    for (int i = 0; i < days; i++) {
        c.add(Calendar.DATE, 1); //add one day to the calendar (so first value is tomorrow)
        datesList.add(new Date(c.getTimeInMillis())); //store each day in the list
    }

    //iterate through the list and do whatever you want with the dates
    for (Date date : datesList) {
        System.out.println(date);
    }
}

Ouput：
