@Imesha - I dont need to get the last Mdified Date of Files, I need the name of the Folder which is latest under a parent folder — Satish Dhanaraj, Nov 29 '16 at 05:34
Get the list of folders in the directory and sort it by timestamp and get the folder name. — Lucky, Nov 29 '16 at 05:35
@SatishDhanaraj But the approach is the same. Even the class name we use is `File`, it can check for directories too. Look at @Saravana 's answer. — Imesha Sudasingha, Nov 29 '16 at 05:48

Use the last modified to sort the directories and get the latest one

    File dir = new File("path");
    File[] files = dir.listFiles();
    File lastModified = Arrays.stream(files).filter(File::isDirectory).max(Comparator.comparing(File::lastModified)).orElse(null);
    System.out.println(lastModified);

using for loop

    File dir = new File("/path");
    File max = null;
    for (File file : dir.listFiles()) {
        if (file.isDirectory() && (max == null || max.lastModified() < file.lastModified())) {
            max = file;
        }
    }
