Hi,

I have two dates:

Date From - 01/01/2008
Date To  - 4/01/2008

How can I output all of the dates between the two. So my output would be :
01/01/2008
02/01/2008
03/01/2008
04/01/2008

Thanks

Use Calendar's add() api...

Calendar obj = Calendar.getInstance();
obj.set(2001, 01, 01);
obj.add(Calendar.DATE, 1);

print the date...
you can keep on adding till you get the required date...

You can come to know the current day, month, year by using get() method of Calendar Class.

probably you can do this below,

Date date1 = DateFormat.getInstance().parse( "01/01/2008" ) ;
Date date2 = DateFormat.getInstance().parse( "04/01/2008" ) ;

Calendar cal1 = Calendar.getInstance();
cal1.setTime( date1 );
Calendar cal2 = Calendar.getInstance();
cal2.setTime( date2 );

while( ! isSameDay( cal1, cal2 ) ){
  //print the cal1 date here
  cal1.add( Calendar.DATE, 1 ) ;
}

public static boolean isSameDay( Calendar cal1, Calendar cal2 ){
   return cal1.get( 0 ) == cal2.get( 0 ) && cal1.get( 1 ) == cal2.get( 1 ) && cal1.get( 6 ) == cal2.get( 6 );
      }

You only need one Calendar:


DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
Date date1 = df.parse("01/01/2008") ;
Date date2 = df.parse("04/01/2008") ;
 
Calendar cal = Calendar.getInstance();
cal.setTime( date1 );
while(!cal.getTime().after(date2)) {
  //print the cal1 date here
  cal.add( Calendar.DATE, 1 ) ;
}

Open in new window

expanding on what cmalakar and others have posted, to get the output you need use something like this:

DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
Date date1 = df.parse("01/01/2008") ;
Date date2 = df.parse("04/01/2008") ;
 
Calendar cal = Calendar.getInstance();
cal.setTime( date1 );
while(cal.getTime().before(date2) || cal.getTime().equals(date2)) {
  System.out.println(df.format(cal.getTime());
  cal.add( Calendar.DATE, 1 ) ;
}
