Any Alternative for this CODE !!!!!!

[Swapna Agarwal]

I do know there are some mistakes in my CODE, but treating this as psudo code, could any one give me the correct code?
My input:
startDate:03/24/2004
endDate: 02/29/2004
Expected output Should return only SUNDAY's between these 2 dates)
03/21/04
03/14/04
03/07/04
02/29/04

Here is my (psudo) CODE

import java.text.DateFormat;
import java.text.ParseException;
import java.util.Date;
import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.*;
import java.text.*;
 
public class MyDate{
 
public static void main(String[] args) {        
        String sDateFormatter = "MM/dd/yyyy";
                java.text.SimpleDateFormat format = new SimpleDateFormat(sDateFormatter);
        // Read and parse input, stopping on a blank input line
        BufferedReader reader =
            new BufferedReader(new InputStreamReader(System.in));
        try {
            System.out.print("ENTER DATE STRING1: ");
            String dateString1 = reader.readLine();
            System.out.print("ENTER DATE STRING2: ");
            String dateString2 = reader.readLine();
            int i;
            Date d1;
            for(i=0,d1=format.parse(dateString1);d1<format.parse(dateString2);d1--,i++){
Date[] dArr;
String s1;
if(d1.substr(0,3)=="Sun"){
dArr[i]=d1;
//d1=d1-7;
}
}
        } catch(IOException ioe) {
            System.out.println("I/O Exception: " + ioe);
        }
}
}

These are the compilation errors:

C:\MyDate.java:27: operator < cannot be applied to java.util.Date,java.util.Date
            for(i=0,d1=format.parse(dateString1);d1<format.parse(dateString2);d1--,i++){

Try this (dt1 is earlier date)

import java.io.*;
import java.util.Calendar;
import java.text.SimpleDateFormat;
class CalendarTest
{
  public CalendarTest()
  {
    try
    {
      BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
      SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
      System.out.println("Enter date 1 (mm/dd/yyyy)");
      String dt1 = input.readLine();
      System.out.println("Enter date 2 (mm/dd/yyyy)");
      String dt2 = input.readLine();
      Calendar cal1 = Calendar.getInstance ();
      cal1.setTime(sdf.parse(dt1));
      Calendar cal2 = Calendar.getInstance ();
      cal2.setTime(sdf.parse(dt2));
      int day = cal1.get(Calendar.DAY_OF_WEEK);
      if(day > 1) cal1.add(Calendar.DATE,-day+8);
      while(!cal1.after(cal2))
      {
        System.out.println(sdf.format(cal1.getTime()));
        cal1.add(Calendar.DATE,7);
      }
    }
    catch(Exception e){System.out.println("Error - terminating");}
    System.exit(0);
  }
  public static void main(String args[]){new CalendarTest();}
}

Thank you so much,Thanks to JavaRanch Forums.
