As far as I know (its been a few month since I looked) this is not (yet?) supported by the google drive API. As a workaround consider installing the native google drive share and write the files you want to upload into the locally mapped shared folder. Then its google drives problem to handle the upload.

can guide you with this

<input id="file-pdf" type="file" name="file-pdf"> 
<button id="submit-pdf">submit</button>

//javascripts

$("#submit-pdf").click(function() {
var inputFileImage = document.getElementById("file-pdf");
var file = inputFileImage.files[0];
var data = new FormData();
data.append("file-pdf",file);
$.ajax({
url:   "uploadpdf",
type:  'POST',
cache : false,
data : data,
processData : false,
contentType : false,
dataType: "json",       
success:  function (response) {        
   if(response.success){
      console.log("ok");
   }else{
       console.log("fail");
   }

}
});    
});

for servlet here function to save to drive

 //parentId  ID folder drive
 public static File insertFile(GoogleCredential credential,String title, String parentId, String mimeType, String filename, InputStream stream) {

    try {
             Drive driveService = new Drive.Builder(httpTransport, jsonFactory, null).setApplicationName("DRIVE_TEST").setHttpRequestInitializer(credential).build();

            // File's metadata.
            File body = new File();
            body.setTitle(title);
            body.setMimeType(mimeType);

            // Set the parent folder.
            if (parentId != null && parentId.length() > 0) {
              body.setParents(
                  Arrays.asList(new ParentReference().setId(parentId)));
            }

            // File's content.
            InputStreamContent mediaContent = new InputStreamContent(mimeType, new BufferedInputStream(stream));  
            try {
              File file = driveService.files().insert(body, mediaContent).execute();

              return file;
            } catch (IOException e) {
              logger.log(Level.WARNING, "un error en drive service: "+ e);
              return null;
            }

    } catch (IOException e1) {
           // TODO Auto-generated catch block
           e1.printStackTrace();
           return null;
    }

  }

I know this question is quite old ,but now google has official support for Java drive api,there is a quick sample to start integrating Drive API with java application. Download drive API client jar files from here

and if you are developing your application from Java SE don't forget to put servlet api.jar on class path or else you will end up with lot of errors.
