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

Question

You can try guava Ordering:

Function getLastModified = new Function() {
    public Long apply(File file) {
        return file.lastModified();
    }
};

List orderedFiles = Ordering.natural().onResultOf(getLastModified).
                          sortedCopy(files);
