Uses of Package
java.util.stream

  • Packages that use java.util.stream 
    Package Description
    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.file
    Defines interfaces and classes for the Java virtual machine to access files, file attributes, and file systems.
    java.util
    Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
    java.util.concurrent
    Utility classes commonly useful in concurrent programming.
    java.util.jar
    Provides classes for reading and writing the JAR (Java ARchive) file format, which is based on the standard ZIP file format with an optional manifest file.
    java.util.regex
    Classes for matching character sequences against patterns specified by regular expressions.
    java.util.stream
    Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.
    java.util.zip
    Provides classes for reading and writing the standard ZIP and GZIP file formats.
