Use getDay() method of java.util.date.

Returns the day of the week represented by this date. The returned value (0 = Sunday, 1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday) represents the day of the week that contains or begins with the instant in time represented by this Date object, as interpreted in the local time zone.

hi,
not that. if i give any date i want the day corresponding the date.
also getDay() is Deprecated.is there any solution?
thanks

[Ajith George]

So what? Use any of the java.util.date constructors to intitialize it with your date. Then use the getDay() to get the corresponding day.

It's deprecated, so you can also try GregorianCalendar(int year, int month, int date)

There are many simple ways to do this without using deprecated methods. One is:

    private static final DateFormat dowFormat = new SimpleDateFormat("EEEEEEEEE");
 
    public static String getDayOfWeekAsString(Date d) {
        return dowFormat.format(d);
    }
