## Uses of Interface
java.nio.channels.Channel

- Packages that use Channel
  Package | Description
  --- | ---
  java.lang | Provides classes that are fundamental to the design of the Java programming language.
  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.
  java.nio.channels.spi | Service-provider classes for the ``java.nio.channels`` package.
