Best way to list files in Java, sorted by Date Modified?

Question

I want to get a list of files in a directory, but I want to sort it such that the oldest files are first. My solution was to call File.listFiles and just resort the list ba

Answer 1

What's about similar approach, but without boxing to the Long objects:

File[] files = directory.listFiles();

Arrays.sort(files, new Comparator() {
    public int compare(File f1, File f2) {
        return Long.compare(f1.lastModified(), f2.lastModified());
    }
});
