## Uses of Package
java.nio

Packages that use java.nio
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.nio | Defines buffers, which are containers for data, and provides an overview of the other NIO packages.
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.charset | Defines charsets, decoders, and encoders, for translating between bytes and Unicode characters.
java.security | Provides the classes and interfaces for the security framework.
javax.crypto | Provides the classes and interfaces for cryptographic operations.
javax.imageio.stream | A package of the Java Image I/O API dealing with low-level I/O from files and streams.
javax.net.ssl | Provides classes for the secure socket package.
