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. -
