plz help with Calendar doubt.. ;-)

[Jack Daniel]

Hi e'body..
my objective is to find the date of first SUNDAY in every month.. and I have written some code..

 

import java.util.*;
import java.text.*;
class Testing{
public static void main(String args[]) throws Exception{
Calendar rightNow = Calendar.getInstance();
SimpleDateFormat sdf=new SimpleDateFormat("MM/dd/yyyy");
rightNow.set(rightNow.WEEK_OF_MONTH, 1);
rightNow.set(rightNow.DAY_OF_WEEK, rightNow.SUNDAY);
String firstSunday=sdf.format(rightNow.getTime());
System.out.println(firstSunday);
}
}
 

This is giving me first SUNDAY of first week.. not first SUNDAY of month..
i.e. giving 08/31/2003 instead of 09/06/2003..
Can Anybody help me on this,.. it would be Great..
I appreciate your help
cheers

try this

import java.util.*;
import java.text.*;
class AllSundays
{
  public static void main(String args[])
  {
    int year = Integer.parseInt(args[0]);
    int month = Integer.parseInt(args[1])-1;  //0-based
    SimpleDateFormat sdf = new SimpleDateFormat("EEEE, dd MMM yyyy");
    Calendar cal = Calendar.getInstance();
    cal.set(year, month, 1);
    if(cal.get(Calendar.DAY_OF_WEEK) > 1) cal.add(Calendar.DATE,7);
    cal.add(Calendar.DATE,-cal.get(Calendar.DAY_OF_WEEK)+1);
    do
    {
      System.out.println(sdf.format(cal.getTime()));
      cal.add(Calendar.DATE,7);
    }while(cal.get(Calendar.MONTH) == month);
    System.exit(0);
  }
}
