Uses of Class
java.nio.charset.Charset
Package
Description
Provides a simple high-level Http server API, which can be used to build
embedded HTTP servers.
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 the classes for implementing networking applications.
HTTP Client and WebSocket APIs
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.
Service-provider classes for the
java.nio.charset
package.Defines interfaces and classes for the Java virtual machine to access files,
file attributes, and file systems.
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 interfaces for tools which can be invoked from a program,
for example, compilers.
