在将字符串格式化为日期对象时遇到麻烦

Question

I have a string that looks like this

Aug 16, 2013,11:30:10

The comma can be replaced by a different separator and the date & time position can be switched.

I am trying to use this format for my SimpleDateFormat(dtString is the String above):

Date d = null;
     try {
         d = new SimpleDateFormat("MMMM dd, yyyy,hh:mm:ss", Locale.ENGLISH).parse(dtString);
      } catch (ParseException ex) {
            Logger.getLogger(MonKaiClientImpl.class.getName()).log(Level.SEVERE, null, ex);
      } 
      return d;

but when I run d.getYear() the result is 113 .

All of the other Date methods return the correct result except .getYear(). Am I missing something? Is my SimpleDateFormatter wrong?

Answer 1

You should not use Date#getYear . It's deprecated.

As for the result you get, it's as specified in the Javadoc:

Returns a value that is the result of subtracting 1900 from the year that contains or begins with the instant in time represented by this Date object, as interpreted in the local time zone.

Use Calendar API instead. Or even better, if you can use 3rd party library, then I would really suggest you to try Joda Time . Or wait for Java 8 to come next year, that has a new Date Time API.

Answer 2

Simple way to check the result of SimpleDateFormat parsing is this

System.out.println(d);

and it shows correct result

the problems is that Date methods interpreting year, month, day, hour, minute, and second are deprecated. See Date API
