How to use “sendDocument” method in Telegram Bot API for send a file using Java

Question

I want to send a file via Telegram Bot API, but I don't know how should I do that in Java (posting multipart/form-data) with provided Telegram Bot HTTP API method, sendDocument .

Here is my code:

        CloseableHttpClient client = HttpClients.createDefault();
        HttpPost upload = new HttpPost("https://api.telegram.org/bot"+Main.token+"/sendDocument?chat_id="+id);

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();

        File file = new File(path);

        builder.addBinaryBody(
                "document",
                new FileInputStream(file));

        HttpEntity part = builder.build();

        upload.setEntity(part);

        CloseableHttpResponse response = client.execute(upload);

Here are the docs.
