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