java - 将 03/03/2015 转换为 3/3/2015 的简单快速方法

Question

我需要将 03/03/2015 转换为 3/3/2015。

这是我的代码:

public class getCorrectDates {

    public static void main(String[] args) throws ParseException {

        List<String> dates = getCorrectDates.getDates("3/2/2014", "03/03/2015");

        System.out.println(dates);

    }

    public static List getDates(String dateStart, String dateEnd) throws ParseException {

        List<Date> dates = new ArrayList<Date>();
        List<String> formattedDates = new ArrayList<String>();

        DateFormat formatter;

        formatter = new SimpleDateFormat("MM/dd/yyyy");
        Date startDate = (Date) formatter.parse(dateStart);
        Date endDate = (Date) formatter.parse(dateEnd);
        long interval = 24 * 1000 * 60 * 60; // 1 hour in millis
        long endTime = endDate.getTime(); // create your endtime here, possibly using Calendar or Date
        long curTime = startDate.getTime();
        while (curTime <= endTime) {
            dates.add(new Date(curTime));
            curTime += interval;
        }
        for (int i = 0; i < dates.size(); i++) {
            Date lDate = (Date) dates.get(i);
            String ds = formatter.format(lDate);

            formattedDates.add(ds);
            System.out.println(ds);
        }
        return formattedDates;

    }

}

输出:

02/28/201503/01/201503/02/201503/03/2015

我需要:

2/28/20153/1/20153/2/20153/3/2015

必须有一种方法可以获取数组中不带零的日期在日期和月份中。我怎样才能做到这一点？

满足以下条件就足够了:

new SimpleDateFormat("M/d/YYYY");

引自java docs :

Number: For formatting, the number of pattern letters is the minimum number of digits, and shorter numbers are zero-padded to this amount. For parsing, the number of pattern letters is ignored unless it's needed to separate two adjacent fields.
