sorting files according to the date in there filename

Posted: Aug 14, 2004 6:42 AM

hello experts,

i am facing some difficulty in sorting the files.
that is i am having files(with datecoulmn in it) in folder.(ex: 01022004datafile.dat).
i want to take the files in the sorting order of the date in the respective filenames.
i am trying with tree map(since for one date more than one file could be there)....how to solve this issue.....
for example

c:\allfiles is the folder
in that
01022004datafile.dat
01022004comfile.dat
02022004datafile.dat
03042004datafile .dat
31012004datafile.dat
31012004comfile.dat

are the files are there
i need for this date these many files are there and in sorted order of date(i.e)
31/01/2004
31012004datafile.dat
31012004comfile.dat
01/02/2004
01022004datafile.dat
01022004comfile.dat
02/02/2004
02022004datafile.dat
03/04/2004
03042004datafile.dat

i am trying with the tree and i am using filename as key and date value as value(since the dates are duplicate it is not allowing me to take it as key).But i cant able to sort according to date values.since the tree can be sorted according to keys not values.......................any solutions is there for this
or in what way we can solve this issue easily........

thankx in advance

Use a TreeMap and date value as the Key and the in the value column have a ArrayList which store all the file names for that date. That should solve your problem I guess
