Uses of Interface
java.util.stream.IntStream
Package
Description
Provides classes that are fundamental to the design of the Java
programming language.
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.
This package contains classes and interfaces that support a generic API
for random number generation.
Classes to support functional-style operations on streams of elements, such
as map-reduce transformations on collections.
