java.util.function.BiConsumer

- Packages that use BiConsumer
  Package | Description
  --- | ---
  java.security | Provides the classes and interfaces for the security framework.

  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.
