Character Streams

• 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.
