Java - get the newest file in a directory?

Question

Does anybody have a snippet of Java that can return the newest file in a directory (or knowledge of a library that simplifies this sort of thing)?

Answer 1

This code works for me well:

public String pickLatestFileFromDownloads() {

        String currentUsersHomeDir = System.getProperty("user.home");

        String downloadFolder = currentUsersHomeDir + File.separator + "Downloads" + File.separator;

        File dir = new File(downloadFolder);
        File[] files = dir.listFiles();
        if (files == null || files.length == 0) {
            testLogger.info("There is no file in the folder");
        }

        File lastModifiedFile = files[0];
        for (int i = 1; i < files.length; i++) {
            if (lastModifiedFile.lastModified() < files[i].lastModified()) {
                lastModifiedFile = files[i];
            }
        }
        String k = lastModifiedFile.toString();

        System.out.println(lastModifiedFile);
        Path p = Paths.get(k);
        String file = p.getFileName().toString();
        return file;

    }
