Answer 1

Use this code

long date = System.currentTimeMillis();

SimpleDateFormat date1 = new SimpleDateFormat("dd-MM-yyyy"); // for current date
SimpleDateFormat time1 = new SimpleDateFormat("kk:mm:ss");  // for 24 hour time
SimpleDateFormat time2 = new SimpleDateFormat("hh:mm:ss");  // for 12 hour time 

String dateString = date1.format(date);    //This will return current date in 31-12-2018 format
String timeString1 = time1.format(date);  //This will return current time in 24 Hour format
String timeString2 = time2.format(date);  //This will return current time in 12 Hour format

Log.e("TAG_1", "24 hour Time - " + timeString1);
Log.e("TAG_1", "24 hour Time - " + timeString1);
Log.e("TAG_1", "dd-MM-yyyy Date format - " + dateString);

than open your logcat to check result.

Answer 2

You used hh in your SimpleDateFormat pattern. Thats the 12 hour format. Use kk instead, that gives you the hours of the day in a 24 hour format. See SimpleDateFormat.

Answer 3

Simply create the instance of Calendar and get 24 hr time by,

Calendar c = Calendar.getInstance();

int Hr24=c.get(Calendar.HOUR_OF_DAY);
int Min=c.get(Calendar.MINUTE);
