[Solved] What is this parameter used for?

Question

Regardless of what I input in the parameter for this, nothing changes??

It’s because the filename argument is not used anywhere in the ReadNumberFile(String filename) method..

As it seems, this parameter (filename) represents the name (or maybe the fully-qualified path) of a file that should be read. If that’s the case, you should change this line to:

r = new BufferedReader(new FileReader(filename));
