Calendar minute not giving the right minute

The code below shows the text of a parsed Date object, and the static field Calendar.MINUTE. Can someone inform why they're different?

The docs say it's supposed to get the current minute value as an int.

EDIT: image removed, code/result updated.

public class Testerson {

  public void print()
  {
      SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm");
      System.out.println("Date time = " + sdf.format(new Date()));
      System.out.println("Calendar Minute = " + Calendar.MINUTE);
  }

  public static void main(String[] args) throws ParseException
  {
      Testerson test = new Testerson();
      test.print();
  }
}

With an output of;

Date time = 08/04/2018 05:49
Calendar Minute = 12

you didn't specify minutes you specified seconds in your date format.

your date time is "dd/MM/yyyy hh:ss" it should be "dd/MM/yyyy HH:mm"

Calendar.MINUTE is a constant (static final). Since, it’s a constant there is no chance it can give you the current minute, as it should change its value every moment. Thus, your understanding is wrong.

The docs says it’s a field number to get and set the Minute of hour. You need to use it to extract the minute value from the calendar instance like below:

calendar.get(Calendar.MINUTE)

Calendar.MINUTE is simply a constant:

public final static int MINUTE = 12;

If you have an instance of Calendar you could get the minute as calendar.get(Calendar.MINUTE).

Calendar has a static constant field named MINUTE. You are printing that constant! That value has nothing to do with that date object.
