  <p><br><br> if i try to add in .addPart("file", bin) under the HttpEntity class, it's show me some error message, <a href="https://stackoverflow.com/questions/22932821/httpclient-post-with-progress-and-multipartentitybuilder">this</a> is my reference link for the .addPart but when i executed the program, my compiler show me this error <br><Br> </p>
  
  <pre><code>Exception in thread "main" java.lang.Error: Unresolved compilation problems:

  <p><br><br><br> i also tested this code and no error show up but the display_name still missing <br><br></p>
