Date/Calendar confusion

Greetings,

Given snippet...

Date today;
today = new Date();
Calendar todayg = Calendar.getInstance();
System.out.println("Date: " + today);
System.out.println("Dateg: " + todayg.SECOND);
System.out.println("Dateg: " + todayg);

The output contains;

Date: Sun Aug 29 17:57:26 GMT-07:00 2004
Dateg: 13
Dateg:
java.util.GregorianCalendar[time=1093827446353,areFieldsSet=true,areAllField
sSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="GMT-07:00",offset
=-25200000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null],first
DayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2004,MONTH=7,
WEEK_OF_YEAR=36,WEEK_OF_MONTH=5,DAY_OF_MONTH=29,DAY_OF_YEAR=242,DAY_OF_WEEK=
1,DAY_OF_WEEK_IN_MONTH=5,
AM_PM=1,HOUR=5,HOUR_OF_DAY=17,MINUTE=57,SECOND=26,MILLISECOND=353,ZONE_OFFSE
T=-25200000,DST_OFFSET=0]

Why does "System.out.println("Dateg: " + todayg.SECOND);" produce a value of
13 when "System.out.println("Dateg: " + todayg);" has SECOND=26 ????

Dazed and Confused...

Because Calendar.SECOND does not represent the seconds value, it is simply a
static (constant) integer representing the field number, which happens to be
the 13th field in Calendar. Your code will always print 13 regardless of the
time the calendar was instantiated. Similarly, todayg.YEAR will print 1,
todayg.MONTH will be 2 ... etc

I think what you're after is todayg.get(Calendar.SECOND)
