Trail: JDK(TM) 1.1 -- And Beyond!
Lesson: What's New in 1.1?

## Networking Enhancements

> The JDK 1.1 release made several enhancements to the networking package, `java.net`: Support was added for selected BSD-style socket options; `Socket` and `ServerSocket` are now non-final, extendable classes; new subclasses of `SocketException` have been added for finer granularity in reporting and handling network errors; and support was added for multicasting.

> The JDK 1.1 release also includes general performance improvements and bug fixes.

### Where to Find Documentation

- To find a list of the new classes and interfaces added to `java.net` to support these enhancements, refer to Additions to `java.net` and to find a list of the APIs deprecated in `java.net` see The `java.net.Socket` Class.

- The `Networking Enhancements` page provides some descriptive material about the changes to `java.net`.
