Packages that use BinaryOperator

Package	Description
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.atomic	A small toolkit of classes that support lock-free thread-safe programming on single variables.
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.
