Uses of Interface
java.util.function.LongBinaryOperator
Package
Description
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.
A small toolkit of classes that support lockfree threadsafe
programming on single variables.
Classes to support functionalstyle operations on streams of elements, such
as mapreduce transformations on collections.
