Question

I have used following line code to display time in 24-Hour format from the Calendar Instance
Everything show correctly, but only problem is while showing time at midnight 12:00 am, It show time as 24:00 instead of showing 00:00. Why this happen anything wrong in my code.

Calendar m_CalInstance = Calendar.getInstance();  
SimpleDateFormat formatter = new SimpleDateFormat("kk:mm");

String timeDisplay = formatter.format(m_CalInstance.getTime());

Answer 1

SimpleDateFormat formatter = new SimpleDateFormat("kk:mm");

should be

SimpleDateFormat formatter = new SimpleDateFormat("HH:mm");

Check this javadoc for more information on SimpleDateFormat
