How do i print 1 as 01?

[Suresh Ramanan]

Hi!

I'm working with dates.
At this point, the design is pretty crude and i'm just making an int 01 and incrementing it for the day.

so i wish to print out the dates in YYYY/MM/DD format.
so i wish to get the date as, say, 2011/02/01
but i'm getting it as 2011/02/1

"02" for month is a string, so no issue there
How do i make sure that 01 is displayed as 01 without getting trimmed as 1?

Best wishes,
Suresh

import java.text.SimpleDateFormat;
import java.util.Date;

public class DateFormates {
    public static void main(String args[])
    {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy/mm/dd");
        Date d = new Date();
        try{
        System.out.println(sdf.format(d));
        
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }

}

I think this will help you

Hi Suresh, take a look at the DateFormat class.

[Rob Spoor]

What are you using to format this date? SimpleDateFormat, or something else?


vinayak jog, there are two things wrong with your code:
1) mm does not print out the month but the minute.
2) format will only throw a NullPointerException so you shouldn't surround it with a try-catch block. It's completely unnecessary. It's the parse method that can throw a ParseException.

This contains a bug. You must use MM, not mm, for months. mm means minutes, not months.

look at the DateFormat class in java API doc
