Question

I have a Object as

private String name;
private int age;
private String country;
// getters and setters

I convert this object into XML using JAXB as following

OutputStream stream = new ObjectOutputStream(new FileOutputStream(getOutputFilePath(document.getUniqueId())));
write(proposal, stream);

and

protected void write(@Nonnull final Document document, @Nonnull final OutputStream stream) throws PersistenceException {
        try {
            jaxbContext.createMarshaller().marshal(document, stream);
        } catch (final JAXBException e) {
            LOGGER.error(e.getMessage(), e);
            throw new PersistenceException("Failed to marshall document " + docment.getUniqueId() + ": " + e.getMessage(), e);
        }
    }

How can I convert this stream into Zip file on disk?
