I/O Enhancements

To support internationalization, the JDK 1.1 release adds character streams to the java.io package. Character streams are like the byte streams that appeared in JDK 1.0 except that they operate on 16-bit Unicode characters rather than 8-bit bytes. In addition, two new byte streams were added to java.io to support object serialization.
Where to Find Documentation

The new character streams are documented in the Reading and Writing lesson which also contains a section on Object Serialization .

For a concise list of the new classes and interfaces added to java.io to support character streams, see Additions to java.io.

For information about converting 1.0 programs that use byte streams to 1.1 programs using character streams refer to How to Convert Code that Uses I/O.

Alternatives to Deprecated Classes and Methods in java.io contains a table that lists the APIs in java.io that were deprecated for 1.1 and their alternatives.
