Hope this helps..

public static void getSundaysInThisMonth(int monthNumber, int yearNumber){
    //int year =2009;
    //int dayOfWeek = Calendar.SUNDAY;
    // instantiate Calender and set to first Sunday of 2009
    Calendar cal = new GregorianCalendar();
    cal.set(Calendar.MONTH, monthNumber-1);
    cal.set(Calendar.YEAR, yearNumber);
    cal.set(Calendar.DATE, 1);
    int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);
    int dateOfWeek = cal.get(Calendar.DATE);
    while (dayOfWeek  != Calendar.SUNDAY) {
       cal.set(Calendar.DATE, ++dateOfWeek);
       dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);
      }
    cal.set(Calendar.DATE, dateOfWeek);

    int i = 1;
    while (cal.get(Calendar.YEAR) == yearNumber && cal.get(Calendar.MONTH)==monthNumber-1)
    {
            System.out.println("Sunday " + " " + i + ": " + cal.get(Calendar.DAY_OF_MONTH));
            cal.add(Calendar.DAY_OF_MONTH, 7);
            i++;
    }

  }
  public static void main(String args[]){
    getSundaysInThisMonth(1,2009);
  }
