Packages that use Consumer
Package
Description
Provides a simple high-level Http server API, which can be used to build
embedded HTTP servers.
Provides classes that are fundamental to the design of the Java
programming language.
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.
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.
Utility classes commonly useful in concurrent programming.
Functional interfaces provide target types for lambda expressions
and method references.
Classes to support functional-style operations on streams of elements, such
as map-reduce transformations on collections.
Classes to support low-level and efficient foreign memory/function access, directly from Java.
This package contains classes for consuming Flight Recorder data.
Provides interfaces for creating tools, such as a Read-Eval-Print Loop (REPL),
which interactively evaluate "snippets" of Java programming language code.
Provides implementation support for building JShell execution engines.
This package contains classes to control and monitor Flight Recorder over Java Management Extensions (JMX).
