Question

In https://github.com/luugiathuy/Java-Download-Manager I cannot find the variable for setting/changing a filename with my own definition, not filename in server.

Answer 1

It does not immediately provide one. According to this code from Downloader, it uses URL.getFile to determine the output file name:

// Get the file name from url path
String fileURL = url.getFile();
mFileName = fileURL.substring(fileURL.lastIndexOf('/') + 1);
System.out.println("File name: " + mFileName);

This field is used at the following particular points in HttpDownloader:

• here

  HttpDownloadThread aThread = new HttpDownloadThread(1, mURL, mOutputFolder + mFileName, startByte, endByte);
  

• and here

  aThread = new HttpDownloadThread(i, mURL, mOutputFolder + mFileName, startByte, endByte);
  

• and lastly here

  HttpDownloadThread aThread = new HttpDownloadThread(1, mURL, mOutputFolder + mFileName, 0, mFileSize);

Why you don’t write your own which supports a custom file name? Surely it would be an interesting exercise for you! Maybe you can write one even better.
