Class Overview
A specialized Reader that reads from a file in the file system.
 All read requests made by calling methods in this class are directly
 forwarded to the equivalent function of the underlying operating system.
 Since this may induce some performance penalty, in particular if many small
 read requests are made, a FileReader is often wrapped by a
 BufferedReader.
