java - How do I save a file downloaded with HttpClient into a specific folder

Question

I am trying to download a PDF file with HttpClient. I am able to get the file but i am not sure how to convert the bytes into a a PDF and store it somewhere on the system

I have the following code, How can I store it as a PDF?

 public ???? getFile(String url) throws ClientProtocolException, IOException{

            HttpGet httpget = new HttpGet(url);
            HttpResponse response = httpClient.execute(httpget);
            HttpEntity entity = response.getEntity();
            if (entity != null) {
                long len = entity.getContentLength();
                InputStream inputStream = entity.getContent();
                // How do I write it?
            }

            return null;
        }

Answer 1

InputStream is = entity.getContent();
String filePath = "sample.txt";
FileOutputStream fos = new FileOutputStream(new File(filePath));
int inByte;
while((inByte = is.read()) != -1)
     fos.write(inByte);
is.close();
fos.close();

EDIT:

you can also use BufferedOutputStream and BufferedInputStream for faster download:

BufferedInputStream bis = new BufferedInputStream(entity.getContent());
String filePath = "sample.txt";
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(new File(filePath)));
int inByte;
while((inByte = bis.read()) != -1) bos.write(inByte);
bis.close();
bos.close();
