How to set 24-hours format for date on java?

Question

I have been developing Android application where I use this code:

Date d=new Date(new Date().getTime()+28800000);
String s=new SimpleDateFormat(\"dd/MM/yyyy          


        

Answer 1

for 12-hours format:

SimpleDateFormat simpleDateFormatArrivals = new SimpleDateFormat("hh:mm", Locale.UK);

for 24-hours format:

SimpleDateFormat simpleDateFormatArrivals = new SimpleDateFormat("HH:mm", Locale.UK);

Answer 2

You can do it like this:

Date d=new Date(new Date().getTime()+28800000);
String s=new SimpleDateFormat("dd/MM/yyyy kk:mm:ss").format(d);

here 'kk:mm:ss' is right answer, I confused with Oracle database, sorry.

Answer 3

Try this...

Calendar calendar = Calendar.getInstance();
String currentDate24Hrs = (String) DateFormat.format(
            "MM/dd/yyyy kk:mm:ss", calendar.getTime());
Log.i("DEBUG_TAG", "24Hrs format date: " + currentDate24Hrs);

Answer 4

Try below code

    String dateStr = "Jul 27, 2011 8:35:29 PM";
    DateFormat readFormat = new SimpleDateFormat( "MMM dd, yyyy hh:mm:ss aa");
    DateFormat writeFormat = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss");
    Date date = null;
    try {
       date = readFormat.parse( dateStr );
    } catch ( ParseException e ) {
        e.printStackTrace();
    }

    String formattedDate = "";
    if( date != null ) {
    formattedDate = writeFormat.format( date );
    }

    System.out.println(formattedDate);

Good Luck!!!

This will give you the date in 24 hour format.

    Date date = new Date();
    date.setHours(date.getHours() + 8);
    System.out.println(date);
    SimpleDateFormat simpDate;
    simpDate = new SimpleDateFormat("kk:mm:ss");
    System.out.println(simpDate.format(date));

Use HH instead of hh in formatter string
