Uses of Package
java.nio.channels

Packages that use java.nio.channels
java.io Provides for system input and output through data streams, serialization and the file system. 
java.lang Provides classes that are fundamental to the design of the Java programming language. 
java.net Provides the classes for implementing networking applications. 
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. 
java.util Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
