Packages that use Consumer Package Description java.lang Provides classes that are fundamental to the design of the Java programming language.java.net.http HTTP Client and WebSocket APIsjava.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.util 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.java.util.concurrent Utility classes commonly useful in concurrent programming.java.util.function Functional interfaces provide target types for lambda expressions and method references.java.util.stream Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.jdk.jshell Provides interfaces for creating tools, such as a Read-Eval-Print Loop (REPL), which interactively evaluate "snippets" of Java programming language code.jdk.jshell.execution Provides implementation support for building JShell execution engines. -
