## Uses of Interface
java.util.function.IntBinaryOperator

- Packages that use IntBinaryOperator
  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 | Utility classes commonly useful in concurrent programming.
  java.util.concurrent.atomic | A small toolkit of classes that support lock-free thread-safe programming on single variables.
  java.util.stream | Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.
