Help me uploading with jsp

[zahid0055]

I used the following code to upload.
It shows file uploaded but the files are stored in bytes.
What can i do now?
I am a beginner and I need a proper solution.

String user=request.getParameter("user");
           String usertype=request.getParameter("user_type");
                        String contentType = request.getContentType();
                        String path=request.getParameter("file");
                        out.println("Content type is :: " +contentType);
                        
                        if ((contentType != null))
                        {
                            
                        DataInputStream in = new DataInputStream(request.getInputStream());
                        int formDataLength = request.getContentLength();
                        byte dataBytes[] = new byte[formDataLength];
                        out.print(dataBytes);
                        int byteRead = 0;
                        int totalBytesRead = 0;
                        while (totalBytesRead < formDataLength)
                        {
                        byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
                        totalBytesRead += byteRead;
                        }
                        String file = new String(dataBytes);
                                               
                        int lastIndex = contentType.lastIndexOf("=");
                        String boundary = contentType.substring(lastIndex + 1,contentType.length());
                       
                        int startPos =0;
                        int endPos =dataBytes.length;
                        String saveFile = "C:\\Users\\RABBY\\Documents\\NetBeansProjects\\testpage\\web\\"+user+"\\" +path;
                        FileOutputStream fileOut = new FileOutputStream(saveFile);
                       
                        fileOut.write(dataBytes, startPos,endPos);
                        fileOut.flush();
                        fileOut.close();
                        out.println("File saved as " +saveFile);
                        }
