files

I've been imparting a Java introduction course for several years. Some slides explain how to read from files and keyboard using BufferedReaders, InputStreams, FileInputStreamReaders etc.

I'm adding slides explaining how to achieve this using more up to date approaches like Scanner.

Should I leave out the old BufferedReaders, InputStreams and FileInputStreamReaders slides altogether, and teach only the new methods, or should I continue to teach these methods for the sake of completeness ?

Will my students benefit from learning how to read from files and keyboard the old way ?
