Google Cloud storage Java XML API file upload and mark uploaded file public

Question

I'm using Google Cloud storage Java XML API to upload file from client into the Google Cloud Bucket , The file is getting uploaded succesfully but i want the uploaded file to be publicly accessible ( the want the file to have public-read permission) , how to set public-read ACL on the uploaded file and thus making it publicly accessible . Here is the code i've used

httpTransport = GoogleNetHttpTransport.newTrustedTransport();


String p12Content = Files.readFirstLine(new File("key.p12"), Charset.defaultCharset());
            Preconditions.checkArgument(!p12Content.startsWith("Please"), p12Content);
            //[START snippet]
            // Build a service account credential.
Path path = Paths.get(MyFilePath);
    byte[] byteArray = java.nio.file.Files.readAllBytes(path);
HttpContent contentsend = new ByteArrayContent("text/plain", byteArray );

GoogleCredential credential = new GoogleCredential.Builder().setTransport(httpTransport)
                .setJsonFactory(JSON_FACTORY)
                .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
                .setServiceAccountScopes(Collections.singleton(STORAGE_SCOPE))
                .setServiceAccountPrivateKeyFromP12File(new File("key.p12"))

                .build();
            // Set up and execute a Google Cloud Storage request.
String URI = "https://storage.googleapis.com/" + BUCKET_NAME + "/myfile";
HttpRequestFactory requestFactory = httpTransport.createRequestFactory(credential);
GenericUrl url = new GenericUrl(URI);
HttpRequest request = requestFactory.buildPutRequest(url,contentsend);
HttpResponse response = request.execute();

Include an "x-goog-acl" header with the value "public-read", like this:

request.setHeader("x-goog-acl", "public-read");

For more, you could check these documentation pages:
