Uses of Interface
java.util.function.Supplier
-
Packages that use Supplier 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.logging Provides the classes and interfaces of the JavaTM 2 platform's core logging facilities.java.util.stream Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections. -
