android - 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 hh:mm:ss").format(d);

I need to get date after 8 hours from current moment, and I want that this date has 24-hours format, but I don't know how I can make it by SimpleDateFormat. I also need that date has DD/MM/YYYY HH:MM:SS format.

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);
