このように私はそれをやって働いた

 //text with the image
                   dos.writeBytes(twoHyphens + boundary + lineEnd);
                   dos.writeBytes("Content-Disposition: form-data; name=text" + lineEnd); // GET text in PHP side
                   dos.writeBytes(lineEnd);
                   dos.writeBytes(UserPost); // mobile_no is String variable
                   dos.writeBytes(lineEnd);

                   //Username with image
                   dos.writeBytes(twoHyphens + boundary + lineEnd);
                   dos.writeBytes("Content-Disposition: form-data; name=usr" + lineEnd); // GET usr in PHP side
                   dos.writeBytes(lineEnd);
