Question

getStartDate方法返回util.Date类型对象。我需要一种方法将“今天”（String类型的Date对象）转换为util.Date对象，格式为MM / dd / yyyy 如果我将“今天”字符串日期格式化为Date对象，我将获得长日期格式。

public Date getStartDate() {

    try {
        System.out.println("startDate" + startDate); // prints Fri Jan 02 00:00:00 EST 1998

        DateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
        String today = formatter.format(startDate);

        System.out.println("today" + today); // prints 02/01/1998 (I need to return Date object  in this format)

        DateFormat formatter2 = new SimpleDateFormat("MM/dd/yyyy");
        Date reformatedDate = formatter2.parse(today);

        System.out.println("reformatedDate" + reformatedDate); // Fri Jan 02 00:00:00 EST 1998

        return reformatedDate; 

    } catch (Exception e) {

    }
    return null;
}

可以做这样的事情来解析日期：

 Format formatter = new SimpleDateFormat("MM/dd/yyyy");
 String dateString = "02/01/1998";
 Date date = null;
 try {
    date = (Date)((DateFormat) formatter).parse(dateString);
 } catch (ParseException e) {
    e.printStackTrace();
 }
 Calendar calendar = Calendar.getInstance();
 calendar.setTime(date);
 int year = calendar.get(Calendar.YEAR);
 int month = calendar.get(Calendar.MONTH);
 int day = calendar.get(Calendar.DAY_OF_MONTH);
 String.format("%02d", month);
 String.format("%02d", day);

 String yourDate = month + "/" + day + "/" + year;

使用模式MM / dd / yyyy将String Date对象转换为util.Date对象
