Renaming file and returning new file pointer

I have a piece of code where I am retrieving a file from a URL and saving it to temp folder. For my use case, I need the file name to be a specific string say 'filename'.

So far the code I have is,

try (AutoDeletingFile fileToUpload = new AutoDeletingFile(pullFile(fileUrl))) {
        fileToUpload.getFile().renameTo(new File(filename));
}

But when I use fileToUpload.getName post rename, it still gives me the original file name. Is there a clean way to get the file pointer of the new file while renaming it?

Because fileToUpload.getFile() only return value, not the reference. So, to update the actual file, you need to:

File file = fileToUpload.getFile();
file.renameTo(new File(filename));
fileToUpload.setFile(file);

That and inside the setFile(), you replace File variable inside fileToUpload with the new one.
