How do I find the last modified file in a directory in java?

Answer 1

    String path = "C:\\Work\\Input\\";

    File dir = new File(path);
    File[] files = dir.listFiles();

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

    for (int index = 0; index < files.length; index++) {
        // Print out the name of files in the directory
        System.out.println(files[index].getName());
    }

}
