| Package | Description | 
|---|---|
| java.nio.channels | Defines channels, which represent connections to entities that are capable of
 performing I/O operations, such as files and sockets; defines selectors, for
 multiplexed, non-blocking I/O operations. |

| javax.swing | Provides a set of "lightweight"
(all-Java language) components that,
to the maximum degree possible, work the same on all platforms. | 
| javax.xml.ws | This package contains the core JAX-WS APIs. |
