Class FileReader is discussed in the following chapters. But now let us look at the classes that descend from Writer, an abstract class from which all character-oriented output streams are derived. All these streams are aimed at receiving 16-bit char data from a program, and sending it to another destination, which may use a different character format (such as UTF format on a disk file).

All these classes are character-oriented output streams. We will be especially interested in FileWriter and PrintWriter classes.
