why Date object returns wrong day?

I am doing this..

String dateString = "12 Nov 2011 12:00"
DateFormat formatter = new SimpleDateFormat("dd MMM yyyy HH:mm");
Date date = formatter.parse(dateString);
System.out.println(date.getDay());

this prints out day as 3 ? why is this happening ? how can I print the correct day?

date.getDay() returns the day of the week as a zero-indexed numeric. In this case it should be Saturday (6).

Your result of Wednesday (3) suggests you are using a variation of the provided code and perhaps forgotten that the month is zero-indexed. e.g.

Date date = new Date(2011, 11, 12, 24, 0, 0); // month is now December, and time ticks over to Wednesday 13th
System.out.println(date.getDay()); // this would produce 3

I believe you want date.getDate().

If you are looking for a String representation of the day, take a look at this example:

Even better, check out the Joda-Time library, it is much more intuitive than the classes provided in the Java SDK. A future version of Java may even adopt a new date framework similar to Joda-Time (JSR-310)

The code you showed should print 6, as this date is a Saturday. On my computer that happens. without further information I cannot deduce more. Is this the complete code you execute? You could print the value of date.toString(), that would possibly give some more information.

Please read the documentation it is worth learning by that.

date.getDay() prints the day of the week. It should display 6 as that is a saturday, not sure how you got 3 as the result.
