What (do you think) is the source of data for a FileReader?

A good answer might be:

A disk file.

Class FileReader will be discussed in the following chapters. Now let us look at the classes that descend from Writer. Writer is 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 to to another destination, which may use a different character format 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.
