So, to put things more clearly, you need to know the most recently created file in a given directory, right ? — SirDarius, Dec 17 '13 at 09:07

File contains lastModified().

    File uploadDirectory = new File("your_download_directory");
    File[] downloadedFiles = uploadDirectory.listFiles();

    Arrays.sort(downloadedFiles, new Comparator<File>() {
        @Override
        public int compare(File fileOne, File fileTwo) {
            return Long.valueOf(fileOne.lastModified()).compareTo(fileTwo.lastModified());
        }
    });

    for (File file : downloadedFiles) {
        if (file.isFile()) {
            // upload file
        }
    }

Yes, you get a list of all files sorted by date. Get the top one and get the name or anything else on the instance. For example file.getName(). – Big Bad Baerni Dec 17 '13 at 09:41

This is only possible in Java >= 7.

Look at BasicFileAttributes.

http://docs.oracle.com/javase/7/docs/api/java/nio/file/attribute/BasicFileAttributes.html

Also check out these links.

An example to get last access time of file in java using jdk1.7

Get the Last Access Time for a File

--- UPDATE BEGIN ---

To get all files in a folder use:

String dirName = "some-name";
File dir = new File(dirName);
File[] files = dir.listFiles();

See also: http://docs.oracle.com/javase/7/docs/api/java/io/File.html#listFiles%28%29

I need to get the name of the lastest downloaded file in hte directory.. From the above links am unable to get the same. – user1787641 Dec 17 '13 at 09:27
@user1787641 Get all the files but sort them by their creationTime, this was my point. What do you expect - to find a built-in method getLastCreatedFile in the API? – peter.petrov Dec 17 '13 at 09:29
I can sort based on the creation time, but how can i get the file name?? ya something similar to getLastCreatedFile(). – user1787641 Dec 17 '13 at 09:37
