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.atomic |
A small toolkit of classes that support lock-free thread-safe
programming on single variables.
|
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.

default IntUnaryOperator |
IntUnaryOperator.andThen(IntUnaryOperator after)
Returns a composed operator that first applies this operator to
its input, and then applies the
after operator to the result. |
default IntUnaryOperator |
IntUnaryOperator.compose(IntUnaryOperator before)
Returns a composed operator that first applies the
before
operator to its input, and then applies this operator to the result. |
static IntUnaryOperator |
IntUnaryOperator.identity()
Returns a unary operator that always returns its input argument.
