# 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.nio.file: Defines interfaces and classes for the Java virtual machine to access files, file attributes, and file systems.
java.nio.file.spi: Service-provider classes for the `java.nio.file` 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).
