Use java.util.Date + java.text.SimpleDateFormat

You can trylong currTime = System.currentTimeMillis();Calendar cal = Calendar.getInstance();cal.setTimeInMillis(currTime);Once you have Calendar instance, you can use/format according to your need.

> Once you have Calendar instance, you can use/format according to your need.No, Calendar is useful when you need to do things like add days, but for formatting a timestamp, all you will properly use is Date and SimpleDateFormat.

I tried and displayed likeSystem.out.prinln(cal.setTimeInMillis(long_time));It is throwing error:Void type not allowed here.Please suggest me

setTimeInMillis has a void return type, so it can't be passed to println.

What you did is like the following:

class X {

public void foo() {}

}

//elsewhere:

X x = new X();

System.out.println(x.foo());

Again, use Date and SimpleDateFormat.

Uselong currTime = System.currentTimeMillis();Calendar cal = Calendar.getInstance();cal.setTimeInMillis(currTime);System.err.println(cal);

To be clear about my question :

I have generated time in Millisseconds , using System.currentTimeMillis().

Now I want to convert that Milliseconds into yyyy-mm-dd HH:MM:SS:SSS format.

How can I do that?

setTimeInMillis() return Type is Void.

I was not clear with your solution.

LOL, have you run this codez? For me, it outputs:

java.util.GregorianCalendar[time=1176827393171,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="America/Los_Angeles",offset=-28800000,dstSavings=3600000,useDaylight=true,transitions=185,lastRule=java.util.SimpleTimeZone[id=America/Los_Angeles,offset=-28800000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]],firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2007,MONTH=3,WEEK_OF_YEAR=16,WEEK_OF_MONTH=3,DAY_OF_MONTH=17,DAY_OF_YEAR=107,DAY_OF_WEEK=3,DAY_OF_WEEK_IN_MONTH=3,AM_PM=0,HOUR=9,HOUR_OF_DAY=9,MINUTE=29,SECOND=53,MILLISECOND=171,ZONE_OFFSET=-28800000,DST_OFFSET=3600000]

Here is the tutorial page regarding formating dates and times: http://java.sun.com/docs/books/tutorial/i18n/format/dateintro.html

> Again throwing the same errorNot if you used Date and SimpleDateFormat.

Once you have Calendar instance, you can useCalendar API to get all the Data(Day, Month and year, TimeZone..), And format according to requirement.
