Foil 38 A Monster Chain

Buffered Reader/Writer classes for Foil 38
The buffered output construct in the previous foil is of limited use since BufferedWriter has so few output methods. Instead, use the "monster" chain:
PrintWriter out =
  • new PrintWriter(
  • new BufferedWriter(
  • new OutputStreamWriter(
  • new FileOutputStream( filename ) ) ) );
which can be shortened somewhat by using FileWriter as shown earlier.
The PrintWriter class defines print(...) and println(...) methods for all primitive types, which unlike other Reader/Writer classes never throw exceptions.
