          /** Global instance of the HTTP transport. */
          private static HttpTransport httpTransport;

          /** Global instance of the JSON factory. */
          private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();


          public static void main(String[] args) {
            try {
              try {
                httpTransport = GoogleNetHttpTransport.newTrustedTransport();
                // check for valid setup
                if (SERVICE_ACCOUNT_EMAIL.startsWith("Enter ")) {
                  System.err.println(SERVICE_ACCOUNT_EMAIL);
                  System.exit(1);
                }
                String p12Content = Files.readFirstLine(new File("XXXXX-privatekey.p12"), Charset.defaultCharset());
                if (p12Content.startsWith("Please")) {
                  System.err.println(p12Content);
                  System.exit(1);
                }
                // service account credential (uncomment setServiceAccountUser for domain-wide delegation)
                GoogleCredential credential = new GoogleCredential.Builder().setTransport(httpTransport)
                    .setJsonFactory(JSON_FACTORY)
                    .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
                    .setServiceAccountScopes(Collections.singleton(DriveScopes.DRIVE))
                    .setServiceAccountPrivateKeyFromP12File(new File("XXXXXXXX-privatekey.p12"))

                    .build();


                Drive service = new Drive.Builder(httpTransport, JSON_FACTORY,credential).build();

                com.google.api.services.drive.model.File  file = new com.google.api.services.drive.model.File();
                file.setTitle("testdd");
                file.setMimeType("application/vnd.google-apps.spreadsheet");
                Drive.Files.Insert insert = null;
                try {
                    insert = service.files().insert(file);
                    file = insert.execute();


                } catch (Exception e) {
                    e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
                }

                com.google.api.services.drive.model.File uploadedDoc = service.files().get("1ZJnkgFXAiUNSBeq3DmhHGqXn7-v37vLg1UsRekRQNjU").execute();

                System.out.println("Title: " + uploadedDoc.getTitle());




                return;

Answer 1

1. Go to you Google Drive. Create some folder, and open "Sharing settings" for it.
2. Add your service email to the list of allowed users and allow it to edit the contents of that folder.
3. Remember folder ID somewhere and use this folder id while uploading files.
4. It will be uploaded in your personal google drive account.
