Convert a string to a GregorianCalendar

问题

How do a I take an input birthday string such as 02 26 1991 and make it into a Gregorian Calendar?

I tried parsing it first but it keeps giving me an error message so I\'m not quite sure what I\'m doing wrong. I also have other input data before this date. One is another string and one is a double value.

回答1:

Use SimpleDateFormat to parse the date and then assign it to a Calendar.

DateFormat df = new SimpleDateFormat("dd MM yyyy");
Date date = df.parse("02 26 1991");
Calendar cal = Calendar.getInstance();
cal.setTime(date);

The third line could be replaced with:

Calendar cal = new GregorianCalendar();

but I prefer the first version.

回答2:

Use a DateFormat as shown here:

Example:

DateFormat dateFormat = new SimpleDateFormat("hh:mm dd/MM/yy");
dateFormat.setLenient(false);
Date d = dateFormat.parse("06:23 01/05/06");

Use the parse() method of the SimpleDateFormat class. You can use setLenient(false) to force strict parsing.
