# Networking Enhancements

> Support for selected BSD-style socket options in the `java.net` base classes. With JDK 1.1, `Socket` and `ServerSocket` are non-final, extendable classes. New subclasses of `SocketException` have been added for finer granularity in reporting and handling network errors. The class `MulticastSocket` moves from `sun.net` to `java.net`. Also includes general performance improvements and bug fixes.
