Uses of Package
java.nio
Package
Description
A Java API for Stream Control Transport Protocol.
Provides for system input and output through data streams,
serialization and the file system.
Provides classes that are fundamental to the design of the Java
programming language.
Provides classfile parsing, generation, and transformation library.
Provides low-level access to memory and functions outside the Java runtime.
The
java.lang.invoke
package provides low-level primitives for interacting
with the Java Virtual Machine.Classes to support module descriptors and creating configurations of modules
by means of resolution and service binding.
HTTP Client and WebSocket APIs
Defines buffers, which are containers for data, and provides an
overview of the other NIO packages.
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.
Defines charsets, decoders, and encoders, for translating between
bytes and Unicode characters.
Interfaces and classes providing access to file and file system attributes.
Provides the classes and interfaces for the security framework.
Contains the collections framework, some internationalization support classes,
a service loader, properties, random number generation, string parsing
and scanning classes, base64 encoding and decoding, a bit array, and
several miscellaneous utility classes.
Provides classes for reading and writing the standard ZIP and GZIP file
formats.
Provides the classes and interfaces for cryptographic
operations.
A package of the Java Image I/O API dealing with low-level I/O from files and
streams.
Provides classes for the secure socket package.
Java™ Smart Card I/O API.
Incubating Feature. Will be removed in a future release.
