20.2. Byte Streams
The
java.io
package defines abstract classes for basic byte input and out-
put streams. These abstract classes are then extended to provide sever-
al useful stream types. Stream types are almost always paired: For ex-
ample, where there is a
FileInputStream
to read from a file, there is usu-
ally a
FileOutputStream
to write to a file.
Before you can learn about specific kinds of input and output byte
streams, it is important to understand the basic
InputStream
and
Out-
putStream
abstract classes. The type tree for the byte streams of
java.io
in
Figure 20-1
shows the type hierarchy of the byte streams.
