title: javax.servlet.http.Part to java.io.File
body: <p>I need help in code which is used to convert javax.servlet.http.Part to java.io.File</p>
  
  <p>I found this useful code but I need help in properly implementing the code.</p>
  
  <pre><code>private void processFilePart(Part part, String filename) throws IOException
      {
          filename = filename.substring(filename.lastIndexOf('/') + 1).substring(filename.lastIndexOf('\\') + 1);
          String prefix = filename;
          String suffix = "";
          if (filename.contains("."))
          {
              prefix = filename.substring(0, filename.lastIndexOf('.'));
              suffix = filename.substring(filename.lastIndexOf('.'));
          }
          File file = File.createTempFile(prefix + "_", suffix, new File(location));
          if (multipartConfigured)
          {
              part.write(file.getName());
          }
          else
          {
              InputStream input = null;
              OutputStream output = null;
              try
              {
                  input = new BufferedInputStream(part.getInputStream(), DEFAULT_BUFFER_SIZE);
                  output = new BufferedOutputStream(new FileOutputStream(file), DEFAULT_BUFFER_SIZE);
                  byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
                  for (int length = 0; ((length = input.read(buffer)) &gt; 0);)
                  {
                      output.write(buffer, 0, length);
                  }
              }
              finally
              {
                  if (output != null)
                      try
                      {
                          output.close();
                      }
                      catch (IOException logOrIgnore)
                      {
                      }

  <p>I tried to edit the code in order to create as a result java.io.File but I always have issues.</p>

  <p>What is the proper way to convert the objects?</p>
