Answer 1

This means that instead of using BufferedReader, one can use the Scanner class, and instead of using BufferedWriter, one can use PrintWriter. BufferedReader is a class in Java that reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, lines and arrays.
