} catch (IOException ex) {
}

try (ZArchive archive = new ZArchive("data.bin.Z")) {
    archive.extract("data.bin");
}

Save to Stream

ByteArrayOutputStream bs = new ByteArrayOutputStream();
try (FileInputStream source = new FileInputStream("alice29.txt")) {
    try (ZArchive archive = new ZArchive()) {
        archive.setSource(source);
        archive.save(bs);
    }
} catch (IOException ex) {
