Java - SimpleDateFormat parses 12:19:00 to 00:19:00

问题

I am trying to parse a string to date, but the output look incorrect: Below is my code.

public static void main(String[] args){      
  Date startDate = new Date();      
  DateFormat formatter = new SimpleDateFormat("dd.MM.yyyy hh:mm:ss");

  try {
    startDate = (Date) formatter.parse("07.10.2012 12:19:24");
  } catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
  }

  System.out.println("Formatted Date " + startDate.toString());
}

Program Output:
Formatted Date Sun Oct 07 00:19:24 IST 2012

Expected Output:
Formatted Date Sun Oct 07 12:19:24 IST 2012

回答1:

You might want to use 24h format instead of 12h format...

H Hour in day (0-23) Number 0

h Hour in am/pm (1-12) Number 12

Yes, formatting characters are case sensitive.

The hh is for when you're doing am / pm, you need HH
