java.util.function.Consumer

Packages that use Consumer

Package	Description
java.lang	Provides classes that are fundamental to the design of the Java programming language.
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.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.
