Recursively ZIP a directory containing any number of files and subdirectories in Java?

Is there an easy way to recursively ZIP a directory that may or may not contain any number of files and any number of levels of subdirectories?

You can use the Java API Specification and How do you recursively traverse through file folders?.

I use the ZipFileSystem implementation in ruby with great success, though I've never used it in java. You might want to check this out:

public final class ZipFileUtil {
    public static void zipDirectory(File dir, File zipFile) throws IOException {
        FileOutputStream fout = new FileOutputStream(zipFile);
        ZipOutputStream zout = new ZipOutputStream(fout);
        zipSubDirectory("", dir, zout);
        zout.close();
    }

    private static void zipSubDirectory(String basePath, File dir, ZipOutputStream zout) throws IOException {
        byte[] buffer = new byte[4096];
        File[] files = dir.listFiles();
        for (File file : files) {
            if (file.isDirectory()) {
                String path = basePath + file.getName() + "/";
                zout.putNextEntry(new ZipEntry(path));
                zipSubDirectory(path, file, zout);
                zout.closeEntry();
            } else {
                FileInputStream fin = new FileInputStream(file);
                zout.putNextEntry(new ZipEntry(basePath + file.getName()));
                int length;
                while ((length = fin.read(buffer)) > 0) {
                    zout.write(buffer, 0, length);
                }
                zout.closeEntry();
                fin.close();
            }
        }
    }
