Sorting a directory content by last modify date

[J_Zanetti]

Hello everyone,

Im trying to sort the content of a directory (a file list) according
to the lastModified attribute of the object.
I get the array of files in this way:

File file = new File(directoryname);
String listoffile[] = file.list();

I would like that this listoffile[] array contains the files sorted by
its lastModified date...
is there any way to do that?

thanks everyone who can help me

Create a suitable java.util.Comparator. Read the
JDocs for same, to see some ways to sort them.

It might also be a good idea to use File.listFiles() instead of
File.list(). Processing a File array instead of a String array will
make your Comparator a lot simpler...

Thank to both of you that answered...I used comparator with array of
files and it works greatly
Thank so much

I think you are making a mistake in using file.list directly. You would
do better to use file.listFiles. You could sort the resulting File[]
according to lastModified() result, and then extract the names in the
right order.
