12:00

13:00

12hrs: ----- 08:00 AM

I Used following code:

public String addTime(int hour, int minute, int minutesToAdd, boolean isAdd) {
    Calendar calendar = new GregorianCalendar(2015, 6, 18, hour, minute);
    calendar.add(Calendar.MINUTE, minutesToAdd);
    SimpleDateFormat sdf = new SimpleDateFormat("hh:mm a");
    String date = sdf.format(calendar.getTime());

Use two date formats: one to parse, and one to format.So your code would be something like

       String _24HourTime = hour +":"+ minute";
       SimpleDateFormat _24HourSDF = new SimpleDateFormat("HH:mm");
       SimpleDateFormat _12HourSDF = new SimpleDateFormat("hh:mm a");
       Date _24HourDt = _24HourSDF.parse(_24HourTime);
       System.out.println(_12HourSDF.format(_24HourDt));
