Reader/Writer classes for Foil 36
Java 1.1 introduced Reader and Writer classes for character streams, which are used to read/write text files.
To construct a character output stream, for example:
PrintWriter out =
  • new PrintWriter(
  • new OutputStreamWriter(
  • new FileOutputStream( filename ) ) );
The OutputStreamWriter constructor takes a byte stream and converts it to a character stream. As a shortcut, use
PrintWriter out =
  • new PrintWriter(
  • new FileWriter( filename ) );
where FileWriter is a subclass of OutputStreamWriter.
